+ Hello
+ I have found bugs from Ubuntu 17.10 (form 16.04 by do-release-upgrade)
a) xrandr fails to change into native resolution
b) disabling Wayland cause “Out of Range” → can’t login at all (no login via
HDMI or virtual TTY:s)
c) X fails to detect old VGA monitor (ViewSonic VA902) native resolution
(this is a persistent bug)
I have used dual monitor setup over a decade, started with Etch and
turned into Ubuntu some years ago. First monitor is connected via HDMI
and second one by VGA. During Ubuntu installations/updates resolution
has been problem, with xrandr etc I have managed situation until now.
I have tested:
1) 16.04 & Radeon works OK with 60 Hz VGA modeline
2) 18.04 & Radeon: HDMI is OK but VGA cant’t go into the native resolution
3) 18.04 & Intel: HDMI is OK but VGA cant’t go into the native resolution
4) 18.04 & Radeon VGA without Wayland is Out of Range and useless
5) 18.04 & Intel & xrandr with “easy” modeline do not work
6) 18.04 & Radeon & xrandr with “easy” modeline do not work
