xf86-video-intel package causes occasional complete freezes of KDE plasma #147

Closed Afsalmc closed 3 years ago

Afsalmc commented 4 years ago

in Gecko Rolling plasma , with default xf86-video-intel package desktop freezes completely with a working audio playback and mouse pointer . Removing this package enables modesettings intel graphics driver from kernel which eliminates this issue completely .

You could also try changing the Plasma compositor rendering method and/or disable screen tearing controls. With that being said, I've also had considerable trouble with the xf86-video-intel driver with Plasma and am considering removing it.

well that is a good news . out of curiosity , what is the need of xf86-video-intel in gecko iso if modesettings is working fine ?

The Intel driver does provide better performance, but for the Plasma edition it's just not worth it due to the instability.

yesterday with modesettings driver vaapi harware accelaration suddenly stopped working . Vlc gave this error with intel-media-driver installed image solved the issue by installing intel-vaapi-driver and editing /etc/profile.d/intel-media.sh to look like : 

# add libva driver path/name exporting for intel media solution
export LIBVA_DRIVERS_PATH=/usr/local/lib/dri
export LIBVA_DRIVER_NAME=i965

and copying /usr/lib64/dri/i965_drv_video.so to /usr/local/lib/dri .

Thanks, I think we can install intel-vaapi-driver out of the box, but I'm not sure if the other tweaks can be included by default without unintended side effects on different hardware configurations.

Good to know . I will report issues with intel HD (Baytrail) while using intel-vaapi-driver( (i965) for hardware acceleration.

Afsalmc commented 4 years ago

Seems fine , no graphics glitches or rendering issues with intel HD (Baytrail) graphics . No noticeable performance decay is found due to the transition from intel driver to modesettigs for day to day usage .

All Plasma spins in the latest set of updates now use Xmodesetting on Intel hardware.
