Screen garbled after KDE comes up since Intrepid Alpha 5

[Thilo-Alexander Ginkel]

Problem:
The X screen is garbled during startup before the login dialog is displayed; doing a vt switch clears the corruption and restores proper functionality.

Tested:
Intrepid a4 (-nv 2.1.10-1ubuntu1, xserver 1.4.99.906-1ubuntu2) - Works properly
Intrepid a5 (-nv 2.1.10-1ubuntu1, xserver 1.4.99.906-2ubuntu5) - Shows the issue
Intrepid a6 (-nv 2.1.10-1ubuntu2, xserver 1.5.0-1ubuntu1) - Shows the issue

Original Report:

Add tag: crash bitesize packaging backport likely-dup needs-testing triage-mentoring-available

This issue is new to Kubuntu Intrepid Alpha 5, i.e., everything still worked correctly with Alpha 4. I can reproduce it reliably by booting the Live CD (x86_64). While usplash shows up correctly, after X has loaded and while KDE is loading the screen becomes garbled - just the mouse pointer shows correctly (see attached photo).
This can be worked around by switching to any text console and switching back using Ctrl+Alt+F7.

Hardware:
Nvidia GeForce 7300 SE

I just re-tested with Alpha 6. Unfortunately, the issue is still present.

If I'm understanding the testing correctly, these configurations were tested:

Intrepid a4 (-nv 2.1.10-1ubuntu1, xserver 1.4.99.906-1ubuntu2) - Works properly
Intrepid a5 (-nv 2.1.10-1ubuntu1, xserver 1.4.99.906-2ubuntu5) - Shows the issue
Intrepid a6 (-nv 2.1.10-1ubuntu2, xserver 1.5.0-1ubuntu1) - Shows the issue

Between alpha 4 and alpha 5, we had the same upstream versions for the driver and server. -nv -1ubuntu2 was just a rebuild against the new server. Between alpha 4 and 5 we had the same upstream xserver; the change was a number of patches added, however they were largely to do with input-hotplug or other things that don't seem to be things that could cause this bug. It might be worth re-testing the xserver without the patches anyway.

Since the -nv version didn't change across these three versions, I'm changing the package to xorg-server; it might be a bug in the driver but so far the evidence doesn't support that.

Hi Thilo-Alexander,

This bug was reported against an earlier version of Ubuntu, can you
test if it still occurs on Lucid?

Please note we also provide technical support for older versions of
Ubuntu, but not in the bug tracker. Instead, to raise the issue through
normal support channels, please see:

If you are not the original reporter, please file a new bug report, so
we can work with you as the original reporter instead (you can reference
bug 268853 in your report if you think it may be related):

If by chance you can no longer reproduce the issue on Lucid or if you

[Thilo-Alexander Ginkel (thilo.ginkel)]

I have not observed this issue in any recent release, so I think we can safely mark this issue as "Fix released".

The nv driver is long since deprecated. Please file a new bug if you can still reproduce this with nouveau.
