Hi. I'm getting display corruption during login on the latest Debian 8 (Jessie), installed from scratch on an emptied hard disk.
I have the MATE desktop environment, and am using the nouveau graphics driver. This didn't happen with my previous OSes (Debian Wheezy, Linux Mint 17.1 or Parabola GNU/Linux bleeding edge). If I boot my machine from cold, having just plugged in: Boot messages progress to lightdm fine All looks normal while interacting with lightdm After entering my login details, before showing the usual MATE desktop elements and wallpaper, the screen is corrupted for a couple of seconds. During that period it is green with various coloured (mostly purple) dots in seemingly-random places. If I then reboot or shut down and start back up without unplugging and waiting for the motherboard to power down, during my next login, rather than the green with purple dots, I get a collage of bits of my previous session's windows (even some long closed before shutdown) displayed. Please can anyone help me to debug and fix this issue? I haven't filed a bug because I don't know where the issue lies at the moment (kernel/systemd/xf86-video-nouveau/...?) I don't mind poking around source code if necessary with a bit of hand-holding. Selected details from lspci, glxinfo and dmesg in the following paste: http://paste.debian.net/169967/ Thanks, Nick -- Sent from my Android device with K-9 Mail. Please excuse my brevity.
