Red Hat Bugzilla – Bug 874475
black stripe over desktop on the right side of screen
Last modified: 2016-05-09 09:28:57 EDT
Description of problem:
I've found strange issue when moving my acer screen into non native mode. Native mode is 1680x1050 but when I switch it to 1680x945 the display is somehow moved to right (so it has black boarder on the left) and it has strange black boarder on the right side that hides its content (I cannot see notification area of gnome shell and I cannot see gnome shell menu on the right.
xrandr says it's set to 1680x945 but monitor says it's 1280x960. This can maybe explain that black boarder as xrandr thinks it's 1680 and draws according to it but screen thinks it's 1280 and do the same according to the different resolution. There is a small black boarder on the bottom which is solid (no content in it).
Version-Release number of selected component (if applicable):
00:02.0 VGA compatible controller : Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller [8086:0126] (rev 09) (prog-if 00 [VGA controller])
connected via dock -> DVI
Steps to Reproduce:
1.obtain lenovo x220 and acer screen (b223PW)
2.set resolution to 1680*945
see whole screen

shouldn't be xrandr advertising just modes that are supported by screen? maybe a bug in xorg-x11-server-utils?

xrandr is not where the "is this mode supported" logic lives, so, no.
Ick, this is the "minimode" nonsense in the kernel. That's the only place a 1680x945 could be coming from.
Just cosmetic, and something I would want to fix in upstream drm directly, moving to 7.1.
Hi, is this problem still present if you try the kernel here?
nope, it looks like it's fixed for some time already. closing
