Public bug reported:
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
