Suddenly, a few hours ago, the same symptoms started on a machine that had been running Debian jessie fine for many months. Also, 'systemctl' reports that gdm runs as expected, but there's no screen content. Also, 'startx' works and launches a Gnome session. 'journalctl' reports nothing unusual (the 'Failed to give slave programs access to the display. Trying to proceed' message seems to be normal.) I don't see anything about a suspicious llvmpipe. Graphics card is an NVidia GeForce GT 430 with the nvidia driver.
This is triple strange. I have no idea what caused this. I didn't change anything except for today's upgrade of cups-related packages, but a similar upgrade on another system did not cause a similar problem. (The upgrade to jessie 8.1 has happened three days ago and did definitely not cause this.) I attached to gdm3 and Xorg processes using gdb and compared the bt with a working system, but was unable to spot any difference. Ideas how to debug this, anybody? -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe". Trouble? Contact [email protected]
