Lenovo Slim 7i Carbon Linux Mint 20 MATE Quick Fix

Touchpad

The touchpad does not work after booting up with Linux Mint 20 MATE, you have few options here:

- Install Ubuntu 20.10 or Fedora 33 (anything with 5.8 kernel)

- Install kernel 5.8 or above from the Ubuntu Kernel PPA Mainline

Install 5.9.8 deb

Pick the 5.9.8 (that is the one I tested) or above from the kernel.ubuntu.com and download to a directory:

$ cd /tmp

$ wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.9.8/amd64/linux-headers-5.9.8-050908-generic_5.9.8-050908.202011101634_amd64.deb

$ wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.9.8/amd64/linux-headers-5.9.8-050908_5.9.8-050908.202011101634_all.deb

$ wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.9.8/amd64/linux-image-unsigned-5.9.8-050908-generic_5.9.8-050908.202011101634_amd64.deb

$ wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.9.8/amd64/ linux-modules-5.9.8-050908-generic_5.9.8-050908.202011101634_amd64.deb

# dpkg -i *.deb

# systemctl reboot

The touchpad should be activated after booting up with the new kernel:

Audio

Sound is not available, please change the following line in /etc/default/grub:

GRUB_CMDLINE_LINUX_DEFAULT="snd_hda_intel.dmic_detect=0"

then, issue the update-grub command:

# update-grub

# systemctl reboot

 

Video

The bundled kernel 5.4.0-[26|54]-generic is able to display 2560x1600 resolution with refresh rate 93 Hz. After fixing the touchpad with the mainline kernel 5.9.8-050908-generic, the display is still showing 2560x1600 resolution, with the refresh rate 60 Hz.

The same issue is found on Ubuntu MATE 20.10 and Fedora 33 MATE. As of writing I cannot find any information on how to fix this in Google searching. The trade off is to set to one of the 16:10 resolution:

16:10 resolution

1920x1200

1680x1050

1440x900

1280x800

Temporary Fix with xorg.conf (10-intel.conf)

This fix only applies for my current Linux Mint 20 MATE with a customized xorg.conf file saved in the location /etc/X11/xorg.conf/10-intel.conf

1. It sets the MATE desktop login screen to 1920x1200 resoluton

2. It creates the above four 16:10 resoluton options, i.e. Control Center | Displays The numbers are obtained from the cvt commands. Other details are from the log files and various commands output during trouble-shooting.

Mate panel disappears

This is something unexpected but it hits me. After logging in there is a Computer icon and a Home icon...

Apparently the mate-panel process is found dead. As long as you run the command mate-panel &, the Mate panel comes back.

For a not so permanent fix (Linux Mint 20.1 should arrive before this year X'mas), create a Startup Applications with the following settings:

Name: mate-panel

Command: /usr/bin/mate-panel

Fix:
Reboot the PC and go into the BIOS Setup
Disable the onboard Ethernet controller
Save and Exit from the BIOS Setup, during POST, turn off the PC
Power on the PC and enable the onboard Ethernet controller
Save and Exit from the BIOS, boot the OS

Rebuild OS does not fix this issue, for some reasons the Realtek onboard Ethernet has this issue occassionally, it happens on two of our Lenovo ThinkCenter M715Q Tiny.

RHEL7.2 totem

Probably one of the easiest way to enable playback of .ts|.iso with totem player on RHEL 7.2

Install the following rpm from the fedoraproject.org:
# rpm -Uvh http://download.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-10.noarch.rpm 


Download and install the following rpm from rpmfusion.org:
rpmfusion-free-release-7.noarch.rpm
rpmfusion-nonfree-release-7.noarch.rpm

# rpm -ivh rpmfusion-free-release-7.noarch.rpm
# rpm -ivh rpmfusion-nonfree-release-7.noarch.rpm

Yum install banshee, this is the one that does the magic!
# yum install banshee

Cinnamon Wallpaper Shell Script

A little shell script to change wallpaper in Cinnamon

Copy the following script and modify it accordingly:
#!/bin/sh
# Script variables
DIR="/home/linuxmint/Pictures"               # Directory contains wallpaper

WALLPAPER=$(ls $DIR/*.png | shuf -n1)    # File extension is set to *.png
echo $WALLPAPER                          # Debug
gsettings set org.cinnamon.desktop.background picture-uri "file:$WALLPAPER"
 

Save the script as wallpaper.sh, and set the file permission to 755.
Then you can run it from your terminal and start debugging.
Once you are happy with it, add it to your crontab (including DISPLAY=:0)
The one below runs every 5 minutes:
*/5 * * * * DISPLAY=:0 /home/linuxmint/script/wallpaper.sh

To debug, you can run the following commands directly:
gsettings set org.cinnamon.desktop.background picture-uri "file:/home/linuxmint/Pictures/snsd01.png"
gsettings get org.cinnamon.desktop.background picture-uri
  
That's it!

CrunchBang 11 "Waldorf" on VAIO P - VPCP115KG

An Aging Laptop
Released in June 2010 with an ATOM CPU Z540, VAIO P shows its age with Mate / Cinnamon desktop. At some point I planned to sell it out but after the announcement that Sony sold its VAIO division, I preferred to keep it and started looking for a lightweight, non Xfce Linux distro. Came across an article from LXF and then did a bit googling, I decided to give CrunchBang a try as it looks very promising with a simple desktop and a dark theme, a bit look like the old days of Linux Mint 5.

Installation
Download the 32-bit Waldorf for Modern PCs torrent and transfer the iso to a USB flash drive using USB image writer. The installation is straight forward and VAIO P displays everything correctly. The only problem I got was the LVM partitioning and poked around the menu for quite a while. In general the installation should finish everything in 10 minutes. Once CrunchBang starts, an interactive shell prompts and guides you through updates and packages installation.

Problem: Screen Flickers
The screen keeps flickering and the following errors are logged in /var/log/messages:
Apr 10 10:31:25 vpcp115kg kernel: [  187.040067] [drm] GMBUS timed out, falling back to bit banging on pin 0 [gma500 gmbus disabled]

The fix is to install latest kernel using smxi, the kernel I am using is:
root@vpcp115kg:~# uname -a
Linux vpcp115kg 3.12-10.dmz.1-liquorix-686 #1 ZEN SMP PREEMPT Fri Feb 7 04:09:24 UTC 2014 i686 GNU/Linux
 
Problem: Audio playing too fast
When playing flac using VLC player or Audacious, the audio playing is too fast. This problem emerges from the liquorix kernels. With the default kernel Linux 3.2.0-4-686-pae the playback of audio is fine.

The fix is to append the following line to /etc/modprobe.d/alsa-base.conf
options snd-hda-intel position_fix=1

Reboot and then run the following commands:
rm -rf ~/.pulse*
pulseaudio -k

< 30 seconds
From power up to Openbox login prompt it takes about 27.4 seconds from my stopwatch!

SO-02D Upgraded to ICS

Background

I bought this phone and a SIM cutter from Amazon Japan in April. In order to use EMOBILE SIM I had it unlocked at local NTT Docomo shop. It was a very unpleasant experience as the staff took more than 10 minutes to check my identity... longer than the time to unlock the phone.

Since most of the bundled Docomo's apps do not run without Docomo's SIM card, and the most important function data-tethering is de-activated for the same reason. This SO-02D was flashed using FlashTool with Generic UK (1257-3921) LT26i ROM (6.0.A.3.67). I was so regret that I should flash it right after the phone was unlocked instead of waiting for 2 more weeks.

Upgrade to ICS

Follow this thread from xda and your SO-02D should have no issue to upgrade to ICS. The only difference from the instruction is my phone gets charge whenever it is connected to my laptop throughout the flash process.

Once upgrade completed, enter the following EMOBILE APNs:
EMnet
APN名　emnet.connect
ユーザー名　emobile
パスワード　emobile

If it is too bothersome, just input the settings of EMnet and PROTOCOL制限なしN. I opt the latter as the default setting. The phone should now be able to connect to internet.


I installed EMnetメール and emobileメール to retrieve EMOBILE's email. emobileメール works without any issue. EMnetメール does not work without switching the APN to EMnet, which is a minor issue as I only receive one email monthly from EMOBILE (i.e. billing!).

Of course, make a backup before doing this!


I did the upgrade on 2nd July, preparation for the upgrade took about 2 hours (installed latest FlashTool and then intercepted by Windows Update), flashing the ROM took about an hour. Spent half day for post configuration.


That's it!

 

SO-02D with EMOBILE SIM Card

My ICS UI

Backup copy-protected DVD using Linux but...

I like watching drama and movie DVD and it is simple to create an iso backup for my favourite on Linux Mint platform. Just use Brasero and it gets the job well done... until few days ago.

When an iso file is created using Brasero, I run the following commands for integrity check as well as generate a new volume ID (mkisofs -V), mkisofs failed to generate a new iso file:

 

Brasero did not report any error during the creation of iso from this DVD. When I opened the iso file from Totem Movie Player and tried to play it, the following error message box appeared:

VLC media player could not play the movie too.

Different programs have been tried but none of them could fix the error (vobcopy, dvdbackup, ddrescue, dd). I even read somewhere saying Linux is not able to cope with the latest DRM, Oops!

Interestingly, the file system from those DVDs tricks the Linux OS about its VOB files with total size closed to 60GB! Further investigation tells me the DVD deployed more than one copy-protected techniques (other than CSS). The article from Gentoo Wiki explains what the problem is and suggests to use IfoEdit to fix the broken IFOs on Windows. After trying to repair several IFO files few times (through wine), I couldn't fix them. In addition, the DVD has 99 chapters, it is too time-consuming to fix all those IFO files, and if I know how!

According to one of the forum I came across it suggested to use DVDFab to rip the DVD and then use imgBurn to take care the rest. Oh no! I need to use Windows (I use it mainly to flash my Xperia phones.)! Therefore, I tried to install DVDFab Qt 8 on Windows 7, then used it to rip the DVD and it did not report any error. Next I used imgBurn to generate iso files, Volia! It worked! I ported those 2 programs into Linux Mint and did similar tests and all were ok.

To install wine:

vpcf1 ~ # apt install wine

Then you need to configure wine to add CD/DVD ROM drive letter:

penguin@vpcf1 ~ $ winecfg

To install DVDFab and imgBurn on Linux, you can just use the following commands (I installed them under /opt directory):

vpcf1 ~ # wine DVDFab8178Qt.exe &

vpcf1 ~ # wine SetupImgBurn_2.5.7.0.exe &
  
Once both programs are installed, rip the DVD using DVDFab, in my case the ripped files are saved under E: (/bittorrent/FullDisc/DVD_VIDEO). Leave the ripped files intact. Next, use imgBurn to generate an iso file from /bittorrent/FullDisc/DVD_VIDEO. When it finishes, your backup is ready!



In summary, to backup a movie DVD, you can:
Method 1
Use bundled Brasero on latest Linux Mint to create an iso.
 
Method 2
Use DVDFab to rip those intentional sector corruption DVD, then use imgBurn to create an iso file. Both can run under Linux through wine. How to use both programs are straightforward.


This morning I bought DVDFab DVD Copy but the license code cannot be registered on Wine.

CyanogenMod 7.1.0.1 on Xperia Arc S

You can find the update instructions from this wiki. I followed it and ended up in boot loop for CyanogenMod 7.1.0.2, so I went for 7.1.0.1 and no problem found. I post the steps and messages and hope you might find it useful here. Please note I installed CyanogenMod on Xperia Arc S (LT18i).



Pre-requisite
Download update-cm-7.1.0.1-XperiaArc-LT15i-signed.zip and validate its md5 checksum. You can find it here. Extract boot.img from the zip file and place it in your Android SDK directory. In my case I place it under dictory /opt/android-sdk-linux_x86/tools/. In addition, copy the zip file to the root of a microSD. A microSD is required for CyanogenMod installation.


Download gapps-gb-20110828-signed.zip and validate its md5 checksum. You can find it here. Copy the zip file to the root of a microSD.


Download fastboot for your respective platform from www.htcdev.com. Registration is required. Place the fastboot binary in your Android SDK directory. Same as where the boot.img is located.


Check if your device's bootloader can be unlocked by dialing *#*#7378423#*#*, select Service info, Configuration, you will find the following:
- IMEI, a 15 digits number, write it down
- Bootloader unlock allowed: Yes


Unlock Bootloader
Run the fastboot command from your terminal, it didn't work for me until I ran it from '../platform-tools' directory instead of '../tools' directory.

Learning RHEL 6

Just a couple of days ago I found a new book of RHCE Certification Study Guide from Michael Jang, I have decided to learn what is new from the latest RHEL 6. This is the second book I read from Michael and is the third book I studied related to RHCE certification. Then I noticed the requirement for labs exercise from it: a computer which supports vmx or svm flags. There is no issue of my newest laptop, a Sony Vaio VPCF13UFX with 8GB RAM and a Transcend SATA 64GB SSD, except it runs Linux Mint 10...

I love how Linux Mint is pre-configured with all codec bundled and you can start watching video and listening music without hours of trouble-shooting. That is the reason I switched from Fedora 10 few years ago. In order to do the lab exercise, I need to put RHEL 6 on it meanwhile installing all the missing components such as Office Suite, multimedia program like mplayer and vlc. No doubt there is no match to the feature-rich OS like LM but at least I hope to get the system a bit closer to what I used to have.

Since there are posts available to get missing components working on RHEL 6, I added it here for my reference as well.
 

Repository
I have tried EPEL and RPM Fusion but eventually I pick RPMforge and Fedora 12 archive. Strictly speaking, F12 is no longer a repository but I learned that there are a lot of RPM were sourced and built from F12 (I might be wrong though). 

Fedora 12 Archive
You can find all Fedora's gpg-pubkey here.
Import the F12 gpg-pubkey with the following command. Later on any RPM downloaded from F12 archive will not issue warning during installation.
[root@vpcf1 ~]# rpm --import https://fedoraproject.org/static/57BBCCBA.txt 

RPMforge
Follow the instructions from their site.



Components

Please refer to its instructions.

I hooked up a Samsung B2440MH monitor with HDMI from my Vaio as a secondary display. The monitor is stood vertically with 3D hardware accelerated. Unfortunately Desktop Effects never works on my secondary display with missing title bar and window handle. Same problem I had on LM 11 that's why I sticked to LM 10 as Compiz works on the primary and secondary display (a miracle!?). Below is my xorg.conf in case someone needs it:

Transmission
Download the following RPM from F12 archive:

[root@vpcf1 ~]# rpm -ivh transmission-gtk-1.93-1.fc12.x86_64.rpm transmission-common-1.93-1.fc12.x86_64.rpm

Stardict
Download the following RPM from F12 archive:      

[root@vpcf1 ~]# rpm -ivh stardict-3.0.1-20.fc12.x86_64.rpm

[root@vpcf1 ~]# rpm -ivh stardict-dic-ja-2.4.2-6.fc12.noarch.rpm

Dropbox
Download it from here. Install it and follow the instructions. I need to comment out all the lines of /etc/yum.repos.d/dropbox.repo as it causes problem with yum update command:
[root@vpcf1 ~]# cat /etc/yum.repos.d/dropbox.repo
#[Dropbox]
#name=Dropbox Repository
#baseurl=http://linux.dropbox.com/fedora/$releasever/
#gpgkey=http://linux.dropbox.com/fedora/rpm-public-key.asc
 
mplayer
Almost trapped into the dependency hell here, but I managed to get it installed successfully.
Download freeglut from F12 archive to fix the dependency problem with libglut.so.3:

[root@vpcf1 ~]# rpm -ivh freeglut-2.6.0-0.2.rc1.fc12.x86_64.rpm
[root@vpcf1 ~]# yum install libcaca

Download cppunit from F12 archive to fix the dependency problem with libcppunit-1.12.so.1:
[root@vpcf1 ~]# rpm -ivh cppunit-1.12.1-3.fc12.x86_64.rpm
[root@vpcf1 ~]# yum install dirac
 
Download esound-libs and audiofile to fix the dependency problem with libesd.so.0:

[root@vpcf1 ~]# rpm -ivh esound-libs-0.2.41-3.fc12.x86_64.rpm audiofile-0.2.6-11.fc12.x86_64.rpm

Then install mplayer with yum install mplayer and its frontend smplayer, as well as mencoder.

Skype
After sorting out all the missing libraries, skype-2.2.0.35-fedora.i586.rpm started with core dump abort error (downloaded from Skype directly). The solution is to use an older 2.1 version through yum. Create /etc/yum.repo.d/skype.repo with the following lines:
[skype]
name=Skype Repository
baseurl=http://download.skype.com/linux/repos/fedora/updates/i586/
#gpgkey=http://www.skype.com/products/skype/linux/rpm-public-key.asc
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-skype
enabled=1
gpgcheck=0
 
Next, yum install skype
Finally, install the following RPM separately (using yum) which is required for skype:

glibc-2.12-1.47.el6.i686
alsa-lib-1.0.22-3.el6.i686
libXv-1.0.5-1.el6.i686
libXScrnSaver-1.2.0-1.el6.i686
qt-4.6.2-20.el6.i686
qt-x11-4.6.2-20.el6.i686

Let's yum does the job and pull other required RPM to your system. To satisfy all the dependencies more than 60 extra i686 RPM are installed!

PMS (PlayStation 3 Media Server)
The latest version is 1.50 build, you can download it from here.
I got 2 issues on RHEL 6.2 with it.

First, the following error msgs were logged:

Error loading libzen: Unable to load library 'zen': libzen.so: cannot open shared object file: No such file or directory  

Error loading MediaInfo library: Unable to load library 'mediainfo': libmediainfo.so: cannot open shared object file: No such file or directory

Download and install the libmediainfo0 and libzen0 from sourceforge.net for your platform (i.e. x86_64.RHEL_6)

[root@vpcf1 ~]# rpm -ivh libzen0-0.4.23-1.x86_64.RHEL_6.rpm
[root@vpcf1 ~]# rpm -ivh libmediainfo0-0.7.52-1.x86_64.RHEL_6.rpm

Second, my PlayStation 3 cannot see it. Just add port 5001 tcp in iptables and restart pms. Or simply disable iptables.




My system is running fine so far except when the lid is closed it logs me out!
