description |
Ubuntu 12.04.5 shows a black screen after login with 3D enabled on
VMware. This is due to a bug in the svga gallium driver's winsys.
It's recently fixed in mesa master commit 2d6206140a, "winsys/svga: Fix
incorrect type usage in IOCTL v2", with a request to backport to mesa
stable, but I'm not sure whether anyone's still maintaining the 10.1 branch.
Due to the severity of the symptoms it would be greatly appreciated if
this fix could be incorporated in the
libgl1-mesa-dri-lts-trusty package as soon as possible.
Unfortunately it's affecting the package on the installation iso. Is there anything that can be done about that?
Thanks,
Thomas |
[Impact]
A user might find Ubuntu 12.04.5 unusable on vmware because he would face a black screen after logging in. Although there is a workaround (disabling 3D) a user may have given up at that point.
Backporting will help the user run the distro after upgrading, so I believe it's highly justified.
[Test Case]
On VMware Workstation 10, Install Ubuntu 12.04.5, preferrably using "easy install".
Boot the VM, log in. You'll see a black screen only.
[Regression Potential]
The bug affects a function that impots a shared buffer to the 3D driver. The function is completely broken by the bug. Even if the patch should introduce another type of breakage, the problem couldn't be much worse than it already is, and should be confined to the specific function in question.
[Other info]
Due to different stack ordering of automatic variables, the bug may or may not be visible depending on the C compiler and the level of optimization used. For example, if -O0 -g is used the bug is not visible on 12.04.5. I have not encountered any symptoms of the bug yet on 14.04.
