Problem occurs only with the mainline kernel which I had installed due to bug 1162732 (computer does not wake up from suspend).
With Raring's current standard kernel I can get into the desired mirror mode via (also awkward): xrandr --addmode HDMI1 1366x768 xrandr --output HDMI1 --mode 1366x768 xrandr --output HDMI1 --mode 1366x768 --same-as LVDS1 Output of "uname -a" with the official kernel: Linux till-twist 3.8.0-17-generic #27-Ubuntu SMP Sun Apr 7 19:39:35 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux ** Also affects: linux (Ubuntu) Importance: Undecided Status: New ** Changed in: linux (Ubuntu) Importance: Undecided => High -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1167231 Title: Xorg crashed with SIGABRT in OsAbort() - Cannot mirror screen in good resolution Status in “linux” package in Ubuntu: New Status in “xorg-server” package in Ubuntu: New Bug description: I have a Lenovo Thinkpad Twist with Core i7 processor and on-chip HD4000 GPU. It has an internal 1366x768 (16:9) display and I have connected and external 1920x1080 (16:9) monitor via HDMI. By default the display gets mirrored with only 1024x768 (4:3) because this is the highest common resolution of the two reported by xrandr. I can switch to a large desktop formed by the two screens with the System Settings (section "Display") with each screen using its native resolution. To get a better mirroring I tried to mirror my screen via the command xrandr --output LVDS 1--auto --output HDMI1 --auto --same-as LVDS1 taken from https://kis.kellogg.northwestern.edu/Pages/ExternalDisplaysLinux.aspx After that both screens showed garbage and do not react to mouse clicks and key presses any more. Unplugging the external screen left the internal with the garbage and I had to SSH in from another Ubuntu machine and run sudo restart lightdm to recover the display of the laptop.
