Public bug reported:
(Not sure if it is xorg)
This looks very very similar to existing bug #949130
The linked video in that bug shows exactly th eproblem, good video.
I am simply filing this here because the machine is mostly unusable and a more
clever relationship to the existing bug is not possible for me here.
Details:
New install ubuntu 12.04 on dell dimension E520, went ok, screen res as
installed 1024x [1000 ish] good however, user wanted larger text and icons =
lower screen res. At lower screen res the display then totally unusable, with
no way to get back!! I did not realise what caused it a the time. I then used
recovery mode to install Lubuntu desktop, which installed ok and looked ok. Byt
again te large icions were requested and like an unkowing dolt I reduced te
screen res, and bam, totaly unusabl;e screen display AGAIN. No way of getting
back to the high res which was working.
After initial ubuntu install (which btw was a warm install from cd but special
in that the home directory was not set to be formattted so home data was
preserved) I almost immediately did updates but only a few available at this
early date.
After Lubuntu desktop install again I did updates but with hindsight I think
th eculprit is th ereduction of screen resolution, or at least its change,
which in this case was always to reduced res.
NOTE
I am filing this bug using i think open box desktop (not ubuntu and not
Lubuntu) because the others hav edisplays (now) which are totally un usable.
Note
It would be *very* useful if I knew a way to reset the screen res to default or
high res using CL from recovery mode, but I dont.
