Heavy screen distortion with Intel graphics

English Hardware

Hello,

I have just upgraded to 42.3 and I have issues with the areas being repainted on my screen:
https://www.dropbox.com/s/oge41qav70pvttd/Screenshot_20170816_210516.png?raw=1

I have an Intel GMA 4500 graphic card and use the default drivers.

How can I fix this? What is wrong compared to 42.2?

Cheers,
Quentin

For a definitive description of your graphics hardware, please run the following and report back

/usr/sbin/hwinfo --gfxcard

Have you tried the following? It’s been reported as a viable workaround for some users.

Create a custom Xorg configuration file eg /etc/X11/xorg.conf.d/20-intel.conf

with the following


Section "Device"
   Identifier "Intel Graphics"
   Driver "intel"
   Option "AccelMethod" "uxa"
EndSection

Be careful with syntax. Once done, restart the X-server.

Thanks for the hint, deano_ferrari. Strangely, my graphics seem to behave normally today…
