Public bug reported: Binary package hint: xorg
After today's upgrade to Natty, my HP ProBook 5320m gets a second builtin screen detected as always connected, which causes some issues and makes real dual-screen setup impossible. It seems to be related to the DisplayPort, as xrandr shows it as eDP1 (the gnome display planel shows it as "Unknown"). Yesterday when I was still on Maverick with 2.6.35-28-generic, it was apparently detecting this differently, and not causing any issue. To summarize the content of the full system logs attached, previously on 10.10, when the laptop was not connected to any external display, xrandr detected the following displays: - LVDS1, connected - VGA1, disconnected - HDMI1, disconnected - DP1, disconnected - DP2, disconnected After plugging in the VGA port to an external LCD, it would simply show VGA1 as connected as well. Now on 11.04, when laptop is not connected to anything, xrandr shows: - LVDS1, connected - eDP1, connected - VGA1, disconnected - HDMI1, disconnected - DP1, disconnected As you can see in the logs, eDP1 is detected with the same capabilities as the builtin LCD (LVDS1). Here are some of the consequences I have seen so far: - I can't turn eDP1 off, as it also switches off the main laptop display (supposed to be LVDS1) - By default eDP1 is virtually positioned on the side of LVDS1, extending the screen estate, except that all things put there can't be seen anywhere. The only workaround I could find is to enable "mirrorring" of the 2 displays. - Because both LVDS1 and eDP1 must be enabled all the time, I can't connect to any external display via the VGA port, because (AFAICS) both CRTC slots of the video card are used. External displays work only if eDP1 is turned off, but that disables the laptop's display... Any help or workaround would be appreciated, and I am ready to try anything that might be useful for further debugging. Thanks!
