--- Comment #31 from Mark Cave-Ayland <[email protected]> --- I also noticed this too: nouveau E[ VBIOS][0000:01:00.0] 0x5c2a[0]: script needs crtc Just for the record, here is what happens with the latest linux-4.1 git repository under a Debian wheezy setup: 1) Reboot laptop into Lenovo BIOS, switch display over from Integrated to Discrete 2) Plug in DisplayPort cable 3) Reboot laptop once again 4) Initial kernel boot seems normal; kernel mode setting seems to work on integrated LVDS supply on boot as normal, i.e. screen blanks and then redraws at a higher resolution during boot with smaller fonts 5) The problem occurs when X starts. Both the integrated LVDS and DisplayPort screens go black and here everything hangs. The laptop is unresponsive. If I do a CTRL-ALT-F1 to switch back to a text console, it takes around 30s for the laptop to react and switch to the new TTY. 6) Once in the text console, the laptop seems responsive once again. While the related bug report mentioned a problem with the cursor under GNOME, I'm actually using KDE (kdm) provided as standard with Debian Wheezy. -- You are receiving this mail because: You are the assignee for the bug.
