[SOLVED] Xorg crashes when opening a folder

This is a follow-up to this topic. Seems the culprit is Xorg - I now caught a Xorg crash under LXDE as well (LXDE was the only DE loading post LightDM). When I click (from PCManFM file manager) on a folder with a large number of media files, the folder contents are shown momentarily and then I got thrown back to lightdm greeter. Any ideas?

Re: [SOLVED] Xorg crashes when opening a folder

Get rid of the dummy driver, use modesetting or intel.

Re: [SOLVED] Xorg crashes when opening a folder

Seth, thanks for suggestion, I tried to experiment with intel driver - LXDE and XFCE both work (GNOME crashing at meta_window_get_monitor), but there is a much bigger problem here - I can't change the resolution from standard 1024x768:
- xrandr doesn't work as there is ("Can't open display")
- none of the DE utils work as no monitor is connected
- Option "PreferredMode" "1920x1080" in xorg.conf does not work either
Any ideas on how to increase the resolution with intel driver w/o monitor connected?

EDIT: Trying to call Xorg -configure crashes as well

Re: [SOLVED] Xorg crashes when opening a folder

I changed to modesetting driver (Driver "modesetting" in xorg.conf) and it worked - resolution changed and no more crashes in either LXDE or XFCE. Thanks Seth.

While GNOME is still crashing on "meta_window_get_monitor" call, this is a different topic, so I will mark this thread as solved.

Re: [SOLVED] Xorg crashes when opening a folder

For completeness sake:
- "Xorg -configure" is (probably "accidentally") broken ever since, deprecated and not supposed to be used
- "Can't open display" simply means that the DISPLAY variable isn't set on the shell you're calling xrandr from
- "none of the DE utils work as no monitor is connected" is kinda beyond me - it should really not matter whether there's a monitor attached, though you'll indeed have to tell the system what resolution to use
