Wine freezes machine on Edgy with VIA unichrome graphics chip

[Nick_Hill]

Steps to reproduce problem:
1) Set up via unichrome graphics using dpkg-reconfigure xserver-xorg
2) Move ~/.wine directory to avoid any experimental contamination
3) Download and unpack notepad 2 from http://www.flos-freeware.ch/zip/notepad2.zip
4) unzip notepad2.zip
5) sync (write changes to file system as it will crash!)
6) wine Notepad2.exe

Error message: LibGL Warning: 3D driver claims to not support visual 0x46

System completely freezes. Any unsaved information on other running programs is lost. Potential file system corruption and data loss. This bug should therefore be marked high priority.

Steps to avoid problem on same system:
1) Insert savage graphics card (disabling VIA unichrome)
2) run dpkg-reconfigure xserver-xorg with all same settings except savage instead of Via
3) wine Notepad2.exe

Error message: libGL warning: 3D driver claims to not support visual 0x4b

Notepad 2 runs normally.

Attached: example xorg.conf file for VIA.
Chip Type: integrated VIA Unichrome on KM400 VIA motherboard chipset.

Given the problem precisely tracks the graphics card/driver, it appears there is a bug in the interface between wine and the VIA xorg driver. Wine worked perfectly on the same system under dapper.

The following provides a workaround:
dpkg -i wine_0.9.9-0ubuntu2_i386.deb (reverting to dapper package)

[Nick_Hill (nick-nickhill)]

Tried reverting wine to edgy and changing graphics driver in xorg from via to vesa. Screen works, wine works, but performance is totally unacceptable.

Only acceptable workaround until compatibility issues are resolved is to use dapper package.

This is potentially related to bug #43154

Also happens in Dapper Drake ( at least for me ) and Gusty Gibbon Tribe 5.

Also in other OpenGL applications. In Gusty Gibbon Tribe 5 glxinfo segfaults.

The problem I believe is in libGL, and possibly in the Unichrome driver.
