http://bugzilla.opensuse.org/show_bug.cgi?id=1099812 Bug ID: 1099812 Summary: modesetting driver: xrandr fails Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: Other OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: X.Org Assignee: xorg-maintainer-bugs@forge.provo.novell.com Reporter: P.Suetterlin@royac.iac.es QA Contact: xorg-maintainer-bugs@forge.provo.novell.com Found By: --- Blocker: --- I'm running TW on a Lenovo T460p (Skylake/HD530), using the modesetting driver. Since at least TW 20180625 (I don't have older snapshots around) I can no longer properly change the resolution of the display. I first noticed when running games that want to go fullscreen, but in a different resolution. I either get an error message like X Error of failed request: BadValue (integer parameter out of range for operation) Major opcode of failed request: 152 (XFree86-VidModeExtension) Minor opcode of failed request: 10 (XF86VidModeSwitchToMode) Value in failed request: 0x193 Serial number of failed request: 46 Current serial number in output stream: 50 and the program dies, or I am left with a black screen and have to switch to a VT and kill the program. One of the latter is the atari800 emulator. If I start it windowed, and then switch to fullscreen, I get only the black window. I can however start it with proper resolution, atari800 -fullscreen -fs-width 2560 -fs-height 1440, then it works. Next I tried xrandr, switching to 1920x1080. This *also* left me with a black screen. I tried logging in on VT, setting DISPLAY and XAUTHORITY, then calling xrandr so switch back, but this did not work. an 'xrandr -s 0' reported an out-of-range index, as there are 0 resolutions available (xrandr without options lists some 20 of them....) I then installed xf86-video-intel and restarted X, then programs and xrandr do work as expected. -- You are receiving this mail because: You are on the CC list for the bug.
