[Bug 472522] Re: Deskpro EN p733 when ubuntu changes screen resolution from 1280*1024 it seems OK but screen is scrambled at reboot
The problem appears to be something wrong with the EDID information
supplied by the monitor. You can see that xrandr reports your monitor
as having dimensions of 0x0mm which obviously is wrong. Elsewhere it
lists it as 300 x 225 mm, but presumably this is enough to confuse it.
Note that these days resolution selection is done in the kernel, not by
X. In fact 'xrandr' is just a simple command line tool that sends the
resolution switching commands through X to the kernel, it doesn't
actually perform the mode switches itself - this is done by kernel mode
selection (KMS). I'll refile the bug against the kernel.
** Description changed:
The system (Deskpro EN p733) is connected to a Philips 107B monitor.
When I try to change the resolution, ubuntu does not recognise the
display type, but it does offer several resolution variants. If I
select 1024*768 (which suits my old eyes much better than the original)
everything works fine - until I reboot. Then I get a screen which seems
to have versions of the display (slightly displaced) on top of each
other. The computer worked fine at 1024*768 with Windows 2000.
Disconcertingly if then I try one of the safe variants of login, I can
eventually get in, BUT my wireless connection is lost.
This sounds to me like the back end end of some peripheral control file
has been lost when the system shuts down.
