Title:
Wrong resolution, and "unknown monitor" since upgraded to 17.04
Status in xorg package in Ubuntu:
New
Bug description:
I've never had a problem like this before. Now, after upgraded to
Ubuntu 17.04 it was already strange to see the boot logo in a kind of
low and fuzzy resolution. And it remained for the LightDM login
screen, also for the desktop after logged on. System setting ->
Display reports "Unknown Display". System settings -> Software &
updates -> Additional drivers shows title "Unknown: Unknown" though
after that "Using Processor microcode firmware for Intel CPUs from
intel-microcode" is active. I could "work the problem around" (see the
end of this writing) but it's really ugly that I need to run a script
every time, when it always worked well on the same machine before this
Ubuntu release.
According to xrandr:
lgb@vega:~$ xrandr
Screen 0: minimum 320 x 200, current 1024 x 768, maximum 8192 x 8192
VGA-1 connected primary 1024x768+0+0 (normal left inverted right x axis y
axis) 0mm x 0mm
1024x768 60.00*
800x600 60.32 56.25
848x480 60.00
640x480 59.94
My GPU:
lgb@vega:~$ lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation Xeon E3-1200 v2/3rd Gen
Core processor Graphics Controller (rev 09)
Monitor is Samsung SyncMaster E2220, standard VGA-cable connection
(this monitor hasn't got any other connector like HDMI or DVI).
My workaround was to create this script and run:
DEV=`xrandr | awk '$2 == "connected" { print $1 }'`
xrandr --newmode "1920x1080" 173.00 1920 2048 2248 2576 1080 1083 1088
1120 -hsync +vsync
xrandr --addmode $DEV 1920x1080
xrandr --output $DEV --mode 1920x1080
After this, the resolution is fine, but still everything reports
"Unknown display" and such. The output of xrandr after running my
script (I played with adding some modes, that is the _60.00 stuff):
root@vega:~# xrandr
Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 8192 x 8192
