Bug Description

Binary package hint: xorg

This bug was reported previously here
https://launchpad.net/distros/ubuntu/+bug/6095/

It was rejected for lack of information. I have attached the requested information to this bug report and the end of the rejected report for the sake of completeness.

This problem still exists in edgy eft, max res gets set to 1280x1024 rather than 1680x1050, leaving black bars on either side (or stretched). To fix, the user has to edit xorg.conf and add 1680x1050 to the list of acceptable "modes".

I have attached the default xorg.conf created at install, a modified xorg.conf that works, and the Xorg.0.log

though a custom modeline isn't needed for it to work, for the sake of completeness the stats for the monitor are located below:

http://supportapj.dell.com/support/edocs/monitors/2005FPW/en/about.htm
VESA, 1680 x 1050(DVI)
Horizontal Frequency (kHz) 65.3
Vertical Frequency (Hz) 60.0
Pixel Clock (MHz) 146.25
Sync Polarity (Horizontal/Vertical) -/+

By the way, I noticed usplash (and console) is limited to 1280x1024 (due to vesafb I think). Is there a chance to use 1680x1050? (or for that matter, many other resolutions, eg 1440x900, 1920x1200, 2560x1600 which are becoming standard in new not-so-expensive lcds).

Possibly this is fixed now in Gutsy as bug 27667, however I need more info to be certain. Can you attach the output from `sudo ddcprobe` and `sudo xresprobe <driver>`?

Tried it in Gutsy Beta (which is older than your patch).

BTW, even though it started in 1280x1024, I had the correct option already configured, so System > Preferences > Screen Resolution showed 1680x1050 (that is more than acceptable to me, no xorg.conf fiddling anymore).

I attach ddcprobe's output and a long tail of Xorg.0.log (with video modes info). Sadly, xresprobe's output was empty (I'm running the driver chosen by the livecd which is radeon, perhaps I'll try it with fglrx next time...

I wasn't sudoing xresprobe (now it's correct).

You can see it's detected as "crt" :(

Please let me know if it still occurs with Gutsy-final. From the ddcprobe output, it looks highly likely that the fix for 27667 may fix this issue.

Now I had some time to install Gutsy and try it.

1- LiveCD's Ubuntu Splash is shown in low resolution, but once installed, the same splash is shown in 1280x1024.
2- X boots straight into 1680x1050 :D :D !!!!!!! (and BTW Compiz Fusion worked flawlessly with my sh**ty Radeon 9600XT with the great Radeon open source driver (I'm about to try the restricted drivers manager and install fglrx, and then try to see if there's an easy way -- say, through Alberto Milone's repo -- to install the latest AIGLX-supporting fglrx).
3- The 6 virtual terminals tty1 .. 6 use low resolution (not even 1280x1024).

Please notice that xresprobe is not reporting "crt" as disptype anymore (it's an empty string now, don't know if that's any good).

I understand that ttys are not a priority (they are not really used by normal users), so that's not important.

Is there a way for the console and splash to support resolutions higher than 1280x1024? Last I checked, vesafb was used and that was its limit...

Thanks Bryce for your work. I attach for reference my new ddcprobe's, resprobe outputs and an 800-line tail of Xorg.0.log.

I don't think usplash supports more than 12x10.

Anyway, closing the bug as fixed!
