Created attachment 127794 Xorg log with glamor warning and server error
On a Toshiba NB505 I have no problem when using the "xf86-video-intel" driver. However when trying to use the "modesetting" driver now embedded into the Xorg server I get:
[ 26.287] (WW) glamor requires at least 128 instructions (64 reported) [ 26.287] (EE) modeset(0): Failed to initialize glamor at ScreenInit() time. [ 26.287] (EE) Fatal server error: [ 26.287] (EE) AddScreen/ScreenInit failed for driver 0 [ 26.287] (EE) [ 26.287] (EE)
I'm using the "i915" linux gpu driver, while lspci shows:
VGA compatible controller: Intel Corporation Atom Processor D4xx/D5xx/N4xx/N5xx Integrated Graphics Controller
And according to the specs under:
https://www.cnet.com/products/toshiba-nb505-n500bl-10-1-atom-n455-1-gb-ram-250-gb-hdd-us/specs
Then:
CPU Intel Atom N455 / 1.66 GHz ... Graphics Processor Intel GMA 3150
Sounds like a bug in the glamor acceleration...
