This problem is fixed in Fedora-11-Snap1-x86_64-Live-KDE I could start up, and switch between, two X servers. Closing this bug. Andrei |
Created attachment 336187 [details] Photo of the error screen Description of problem: Hi, An attempt to use second X server (via the "Switch user" Gnome or KDE menu or otherwise) locks console on my system. Usually I can revive the keyboard by ssh-ing into the machine and issuing "chvt <N>". This is what I did to demonstrate the problem in a simple setup: Boot into runlevel 3. Login (non-root) onto tty2 and tty3 [tty2] $ xinit /usr/bin/xterm -- /usr/bin/X :2 Works as expected. Switch to tty3. [tty3] $ xiint /usr/bin/xterm -- /usr/bin/X :3 OK, got an xterm on :3 An attempt to switch to the server on :2 gives black screen. Can't switch to any tty via keyboard now. Connected to the system via ssh, did "chvt 1" as root. The console is back to life. On tty3, there is the following error message: X: intel_bufmgr_fake.c:1372: intel_bufmgr_fake_evict_all: Assertion `((&bufmgr_fake->fenced)->next == (&bufmgr_fake->fenced))' failed. xterm: fatal IO error 11 .... on X server ":3.0" xinit: connection to X server lost. I am attaching a photo of the error screen, log files of the two X servers, and output of "lspci -vvv". The machine is a Lenovo x200s laptop with Intel GMA 4500MHD. Fedora 10 with current updates, kernel-2.6.27.19-170.2.35.fc10.x86_64 No xorg.conf Version-Release number of selected component (if applicable): xorg-x11-drv-i810-2.5.0-4.fc10.x86_64 How reproducible: always Steps to Reproduce: start 2 X servers Actual results: server crash, console locked Expected results: both X servers working Additional info:
