video upgrade issues

recent upgrade of


caused text/screen to become buggy unreadable and a permanent black dashed line on right side of screen.

find video/graphics related updated packages:
nano /var/log/pacman.log

ls /var/cache/pacman/pkg/

Proceed to downgrade

cd /var/cache/pacman/pkg/

sudo pacman -U libinput-0.17.0-2-i686.pkg.tar.xz mesa-10.5.7-1-i686.pkg.tar.xz mesa-libg-10.5.7-1-i686.pkg.tar.xz xf86-video-intel-2.99.917-5-i686.pkg.tar.xz

After restart, fixed

However is there a better solution than downgrade?

Re: video upgrade issues

I confirm the problem after upgrading to mesa 10.6.0-1 under the Intel Graphics, with the work of the VA-API

My configuration:

System:   4.0.6-1-ck x86_64 (64 bit), (tested also 4.0.5-2), Desktop: KDE Plasma 5.11.0 (Plasma 5.3)
CPU:       Dual core Intel Core i5 M 450 (-HT-MCP-) cache: 3072 KB
Graphics:  Card: Intel Core Processor Integrated Graphics Controller
           Display Server: X.Org 1.17.2 driver: intel Resolution: 1920x1080@60.00hz
           GLX Renderer: Mesa DRI Intel Ironlake Mobile GLX Version: 2.1 Mesa 10.6.0

Description repetition of the problem:

  1. Metod 1

    • - install mesa 10.6.0-1 and mesa-libgl 10.6.0-1

    • - install mpv and configure it:

    • - play any video,

  2. Metod 2

    • - install mesa 10.6.0-1 and mesa-libgl 10.6.0-1

    • - install kodi

    • - enable VA-API (Settings > Video > Acceleration)

    • - play any video

Symptoms: display slows down and freezes

Tested on:
- xf86-video-intel 1:2.99.917+364+gb24e758-1 and 2.99.917-5
- AccelMethod, SNA, UXA, glamor
- Linux 4.0.6 and 4.0.5-2

It helps only downgrade to mesa and mesa-libgl to 10.5.7-1

Please test and confirmation

Re: video upgrade issues

creating 20-intel.conf using uxa caused xorg to crash and could not launch desktop environment

downgrading mesa and mesa-libdl only while keeping others upgraded  made no difference buggy unreadable display terminal.

however, testing individual downgrades, downgrading xf86-video-intel (1:2.99.917+364+gb24e758-1> 2.99.917-5) only, while keeping other 3 packages upgraded, the display is working fine.

Re: video upgrade issues

Sorry if this should be a new thread but it seems maybe related, the upgrade of xf86-video-intel (2.99.917-5 -> 1:2.99.917+364+gb24e758-1) caused screen tearing to appear for me even with Option "TearFree" "true" in /etc/X11/xorg.conf.d/20-intel.conf

downgraded xf86-video-intel to 2.99.917-5 and tearing dissapeared

Re: video upgrade issues

Just an FYI, UXA in the Intel driver is not really supported anymore. It is actually being removed bit by bit. Also their VA-API hardware video acceleration implementation has been unreliable in the past year and a half. It breaks randomly from updates, then works again in the newer versions and then breaks again, etc. Try disabling HW acceleration in the video player (VLC can do this) until newer version of xf86-video-intel or libva-intel-driver is available. Sometimes the ffmpeg-based players work with HW accleration enabled and the GStreamer-based ones do not, and sometimes its the other way around. Try them both and if the result annoys you - downgrade until there's an upgrade to a newer version.
