glxinfo causes X to crash on thin-client

[Francis Giraldeau]

Binary package hint: xserver-xorg-video-openchrome

When running the commande "glxinfo" on a workstation with openchrome supported hardware and openchrome driver, X server crash. The workstation is configured as a thin-client.

The last message in the Xorg.log file is :

 getDrawableInfo failed to look up window

I'm not able to reproduce the problem when running glxinfo directly on the workstation as a local process, but only when running from a distant host.

Server and client are running ubuntu hardy.

 xserver-xorg-video-openchrome 1:0.2.901-0ubuntu4
 xserver-xorg 1:7.3+10ubuntu10

The client machine is a Wyse V50LE Unichrome Pro VGA card

01:00.0 VGA compatible controller: VIA Technologies, Inc. UniChrome Pro IGP (rev 01)

Hi francis-giraldeau,

Thank you for taking the time to report this bug and helping to make Ubuntu better. You reported this bug a while ago and there hasn't been any activity in it recently. We were wondering is this still an issue for you? Can you try with the latest development release of Ubuntu? (ISOs are available from cdimage.ubuntu.com)

If it remains an issue, could you also attach a new /var/log/Xorg.0.log?
Thanks in advance.

The output of lspci -vvnn would also be worth having.

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.
