 Posted: Fri Oct 19, 2018 10:14 am Post subject: [SOLVED] rendering issues on UHD Graphics 630 |
 |
|
I'm building a new Thinkpad P52 from scratch on Gentoo
I experience startnge rendering issues with gnome terminal (suddenly black or transparent background) and with google-chrome (all kinds of weird windows appear, no text input visible).
I suspected rendering and emerged virtualgl and tested with glxspheres64 - I didn't get the nice animation I expected. The picture seems to switch berween 2 frames - i.e. no animation, rotation of the daisy and flying spheres, but the starting terminal shows 60 frames per second,
I use VIDEO_CARDS="intel i965"
I'm out of ideas about where to debug further

The natural way is to try modesetting driver, but it doesn't work at all. the X server is killed:
| Code: | [ 3941.070] (II) Module modesetting: vendor="X.Org Foundation"
[ 3941.071] compiled for 1.20.2, module version = 1.20.2
[ 3941.071] Module class: X.Org Video Driver
[ 3941.071] ABI class: X.Org Video Driver, version 24.0
[ 3941.071] (II) modesetting: Driver for Modesetting Kernel Drivers: kms
[ 3941.071] (WW) Falling back to old probe method for modesetting
[ 3941.071] (II) modeset(1): using default device
[ 3941.071] (II) modeset(G0): using drv /dev/dri/card0
[ 3941.071] (WW) VGA arbiter: cannot open kernel arbiter, no multi-card support
[ 3941.071] (EE) Screen 0 deleted because of no matching config section.
[ 3941.071] (II) UnloadModule: "modesetting" |

update: glxgears don't work either. The gears appear to be stuck and moving forward/backward (alternating between 2 frames), no rotation.
They kind of rotate when I resize the window. |

I managed to start modesetting driver by specifying BusID in xorg.conf.d for the device.
I do have optimus laptopm but I it is not my 1st one.
Previous Thinkpad T540p didn't require any xorg.conf.d modifications.
I've also put BusID for bumblebee xorg.conf.nvidia and my optirun started to work flawlessly.
Apparently xf86-video-intel has a serious bug
