http://bugzilla.suse.com/show_bug.cgi?id=935419 Bug ID: 935419 Summary: with 3 monitors on 2 graphic cards Xorg crash on xrandr change Classification: openSUSE Product: openSUSE Factory Version: 201505* Hardware: Other OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: X.Org Assignee: xorg-maintainer-bugs@forge.provo.novell.com Reporter: tcech@suse.com QA Contact: xorg-maintainer-bugs@forge.provo.novell.com Found By: --- Blocker: --- I found some spare monitor and graphic card so I wanted to put that all together. I started with 2 monitors attached to Intel graphic card (probably onboard). In BIOS is integrated Intel graphics set as the primary video. HDMI 1 and HDMI 2 +--------+ +-----+ | 1920 | |1080 | | 1080 | |1920 | +--------+ | | | | +-----+ $ xrandr --output HDMI1 \ --mode 1920x1080 --primary \ --output HDMI2 \ --mode 1920x1080 --rotate left --right-of HDMI1 I connected third monitor to spare Radeon graphic card. I tried to write my configuration by hand but in the end I wiped all my changes to /etc/X11/xorg.conf.d and did reboot. Luckily XRandr shown all the monitors as hoped. Unfortunately, when I pass command like this, Xorg dies with SIGSEGV. $ xrandr --output DVI-1-0 --mode 1280x1024 --rotate left --right-of HDMI2 I tried to put it all into single command with the same result. Any workaround would be appreciated as well.
