ubuntu 8.10 detects display incorrectly for trident cyberblade

[Dale Schaafsma]

Binary package hint: xorg

8.04 allows use of displayconfig-gtk to modify to the correct driver...8.10 appears to require hand modification of xorg.conf file?!

The lcd panel got 800x600 expected 1024x768
Refresh got 56hz/60hz expected ??

$ lspci -nn | grep VGA
01:00.0 VGA compatible controller [0300]: Trident Microsystems CyberBlade/XP [1023:9910] (rev 63)

This command apparently isn't present anymore, the wiki at https://wiki.ubuntu.com/X/Reporting requested it:
$ sudo ddcprobe

$ xrandr

apparently this should be in xorg.conf (the revised xorg.conf does correctly display 1024x768)

Still broken in Karmic.

I think this is upstream in Xorg, but I also think the Trident driver's so old that upstream won't care unless someone submits them a good patch - so if we don't want this broken in Ubuntu we'll have to fix it ourselves first and submit the patch.

This bug report was filed against an old version of Ubuntu.
Can you confirm whether this is still an issue in natty?

If you don't mind, it would be very helpful if you could update the bug
report in launchpad to 'Fix Released' if it is no longer an issue for
you, or if it is still occurring under natty, please tag the bug 'natty'
so it's easier for us to track.

We're closing this bug since it is has been some time with no response from the original reporter. However, if the issue still exists please feel free to reopen with the requested information. Also, if you could, please test against the latest development version of Ubuntu, since this confirms the bug is one we may be able to pass upstream for help.
