--- Comment #4 from mondane.woodworker@gmail.com --- Created attachment 101515 --> https://bugs.freedesktop.org/attachment.cgi?id=101515&action=edit Output of glxinfo as requested. The output is made after the problem occured.
The glxinfo command had to be typed with a black screen. When using SSH, a message was showh the display couldn't be opened, which makes sense.
