Hello:

I am having resolution problems. I have been searching online for a
solution but I have found none that work for me. System info:
Dell 1.7M CPU
OS Ubuntu 7.10
Dual Boot XP/Ubuntu each on separate drive
Monitor Dell E772C
Graphics Card Intel 845
Driver VESA -generic VESA compliant card
I am marginal at CLI.

Problem started last week. System kept reverting to default
resolution. I find default resolution very hard to read over time. I
found and went through the resolution edit. System came up and said
the monitor was running on minimum resolution. I tried several times to
get the system back up and was only able to get it back up by accepting
the minimum (640 X 480) resolution. It appears to be locked in now as I
can not change it from the screen resolution app. 640 X 480 is the only
choice. While in this resolution I ran into several problems with being
able to see the bottom of some windows on the screen. This morning the
top panel ended up on the left hand side. I tried to get it back to the
top, but is so compressed I can not get a handle on it. I believe I
have to get the resolution problem fixed so I can go onto other
problems. I found online Xorg-edit
"http://linuxappfinder.com/package/xorg-edit"; and downloaded it to
"Applications", however I can not open it because the top panel is on
the left hand side and so compressed that Applications will not open.

All help greatly appreciated.

I am not an expert on these things, but I have found that with Ubuntu 7.10, gutsy, sometimes the easiest way to fix the video is to start over. What I mean is go into a terminal, using the following commands rename the X-Org file, then delete the rest and let the system rebuild it.

Start with
$ cd /etc/X11
$ sudo cp xorg.conf.? xorg.conf.keepthis - ? is whatever the highest
number is, 1,2,3...
$ sudo rm xorg.conf
$ sudo rm xorg.conf.failsafe - or similar
$ sudo rm xorg.conf.?

now close the terminal window, and restart your system, using the quit,
restart. When it restarts, it will rebuild the file and you should be
able to reset the resolution.

Also, check out the bug reports in launchpad:

https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/3731

It starts out on Ubuntu 5.10, but goes on into Ubuntu 7.10

good luck,



Charlie:

Thank you for the info. I will get to it as soon as I can. Looking at
the chronology of this thread it seems I was looking up bugs about the
same time you were. I have come across several references to an Intel
i915 driver which seems to be a more up to date driver, which corrects a
lot of problems of the previous drivers.

I am using a Dell which was originally an XP machine. I have had to dump
the Lexmark printer for an HP. It seems that Ubuntu has been fighting
this driver/resolution problem for about 30 months. I will try the
suggested solutions. However I wonder if there is a better graphics
card. The i845 I have is several years old. I guess I will start
searching for info on drivers for E772C Dell monitors.

Might be worth going to Dell's support site on the monitor. They may
have a Linux driver listed. Even for older equipment, they now list some
drivers for us. As for the i845, I think you may have better luck with
the "-intel" driver. If I recall correctly, that contains the updated
i915 drivers, which are backward compatible and more cooperative than
the i810 drivers. I had to use the -intel driver on one of my other
units with the i810 chipset. Something to keep in mind for later, maybe?

good luck,

Charlie:

System running properly on i815 driver and backed up. 815 was the only
Intel driver on the list in GUI edit. Will probably have to chase down
i915 driver at some time, and learn how to load it.
