Edgy Graphics Problem

[irishScott]

I posted about this a few months ago, but got lazy and stayed with Dapper. Now I can't find the thread. Anyways, I try to install Edgy on my Acer TravelMate 8204, and when X boots up off the liveCD it looks like this.

Any ideas?

GPU: ATI Mobility Radeon X1600 256MB Dedicated

Yep. That's crappily bizzare.

Be sure to file a bug about it so the developers know.

Check out the /etc/X11/xorg.conf file and make sure that the correct settings are there for your monitor.

You can probably get to it by going ctrl-alt-F1
Then logging in.

The file is divided up into sections. The important section here is the 'monitor' section.

This is what I use:
Section "Monitor"
Identifier "Generic Monitor"
Option "DPMS"
EndSection


That's the most 'correct' way to do it. This way it's dynamicaly configured from teh DDC values the monitors use themselves. Doesn't always work though.


Also if you want to manually put in the range of horizontal and vertical syncs you can add these lines to that section:

HorizSync 31.5 - 48.5
VertRefresh 60.0 - 60.0

Of course edit the values to match your monitor.


Eventually it will look something like this:

Section "Monitor"
Identifier "Built-in LCD"
HorizSync 31.5 - 48.5
VertRefresh 60.0 - 60.0
EndSection

Since your dapper install works you can probably just copy the configuration, or at least the monitor section from that....



sometimes people like to add 'modelines' settings for LCD displays.

These are a throw-back to ancient XFree86 3.x days.. they allow a high degree of control though.
If you have modelines present in your xorg.conf and they aren't working then delete them.

Realy I don't know why on earth people use them. They are only needed rarely. Sometimes they can provide a better picture quality or something like that, but if they are causing issues then get rid of them.


Also before editing files make a copy of them.
So if you edit something and it makes it worse or you have a typo you can't figure out then you can copy the old one back over the new one and undo any changes.
However since this is a live cdrom then it'll just get regenerated each time you reboot so it's not a big deal.


edit:

Oh, the 'identifier' line is important because it's used to reference that monitor section in other parts of the configuration.

Yeah, copy the monitor section, but is also helpful if you can post you xorg.conf here for us. probably your sync is under 60Hz or above 75Hz. Copy the text and post here.

Try pressing Ctrl+Alt+F1 and swtching to the console, then Ctrl+Alt+F7 to switch back. There was a similar problem going around when trying to install Feisty.

nvm. I was using a friend's CD. Checked it for errors and 8 checksums failed. I burned my own disk and it works perfectly.

Tell him to burn his CD's at lower speeds, or, get a new CD/DVD burner. -_-
