Description Stewart Adcock 2005-06-21 14:28:06 UTC 
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.7.8) Gecko/20050524 Fedora/1.0.4-4 Firefox/1.0.4

Description of problem:
Upon selecting the graphical install, the display is garbled (many vertical artifacts, shadowing of content, flickering, mouse pointer seems to be in three places...).  The display appears too long (vertically) to fit on the physical display - use of "linux lowres" fixes this, but the display is still garbled.  The content can, just about, be read.

The text-based install works normally but when X starts upon first boot, the display is similarly corrupted.

Once the corrupted display occurs, the text console screens are also garbled (hideous colours, rectanglar artifacts, nonsense characters located seemingly randomly on screen, no typing is visible but cursor appears to move correctly).

Partial Workaround:
1. Perform text-based install.
2. Endure the garbled display during the first-boot setup.
3. Use system-config-display to manually select correct monitor type (Dell D1226H).
4. Reboot.  (Just restarting X is insufficient.)

Note that the console screens are still corrupted once X begins.

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. Attempt graphical install from CD set.

Or:

1. Perform text-based install.
2. After install, boot as usual.
3. Start X, manually or otherwise.



Actual Results:  Display garbled, as described.

Expected Results:  Display not garbled.

Comment 1 Mike A. Harris 2005-06-22 21:37:45 UTC 
Please review bug number 161242 everyone, and try using the libvgahw.a module
that is linked to from that bug report.  This is just a hunch I'd like
to test to see if the problem reported on Matrox and Intel hardware is also
causing problems on Trident and other hardware.

Anyone who can test this and provide feedback, would be greatly appreciated.

Thanks in advance.

Niether of the fixes outlined in bug 161242, comment #94 fix this problem.  In
fact, the display is subjectively worse with the xorg-x11-6.8.2-43 rpms due to
increased flickering.
