[Kernel-packages] [Bug 1787861] Re: Displays not detected/positioned correctly when disconnected/reconnected

Previously, this was all working correctly: I have 3 displays connected to an nVidia GT 730. VGA-0 (an old 21-inch CRT) is never enabled (just haven't got around to removing it). DVI-D-0 is the primary display, always connected and turned on, in 1920x1080 60hz. HDMI-0 is a secondary display (actually, linked to my AV receiver and then to my 55" HDTV), and it is turned on when I want the big screen (1920x1080 60hz, positioned to the left of the primary), turned off the rest of the time. Now, whenever I turn off my secondary HDMI display, my third (VGA) display is automatically enabled. Furthermore, when I then turn the secondary display back on, it is set to the wrong mode (interlaced at 30 Hz instead of progressive scan at 60 Hz) and in the wrong position (to the right of the main display, when I want it to the left). Running the correct 'xrandr' command to reset all three displays to the correct conditions instead results in random behavior--instead of a 3840x1080 screen, with the primary display offset to +1920x0, I usually end up with both displays set to span the entire 3840x1080 area, offset to +0x0 (so they're mirroring each other). Sometimes the VGA display remains turned on with a random (not actually displayable) resolution, sometimes it does not. Trying to force the displays into the correct mode with further 'xrandr' commands does not work; I have to reboot the machine to get the displays back to where they belong. This is the 'xrandr' command that SHOULD reset the displays to the correct modes/positions (the primary DVI display is already in the correct mode, so I don't specify that): xrandr --output VGA-0 --off --output DVI-D-0 --primary --output HDMI-0 --size 1920x1080 --rate 60 --left-of DVI-D-0 Occasionally, it does work correctly, but most of the time, it does not (see above). Under 16.04 LTS, I did have an issue for a long time where the secondary HDMI display would be set to an interlaced mode when I turned it back on (but otherwise, everything was correct--and a simple 'xrandr -output HDMI-0 --auto' fixed it); that problem was corrected with a kernel upgrade a short time ago (maybe 3 months?-- unfortunately, I never filed a bug and just lived with it, so I'm not sure exactly when the problem went away, either). Attached is the output of 'xrandr' with everything set correctly.

[Kernel-packages] [Bug 1787861] Re: Displays not detected/positioned correctly when disconnected/reconnected
I really hate intermittent bugs. The previous two times (before just now) that I turned the AV receiver & TV back on, everything reverted to normal (VGA-0 off, HDMI-0 on at 1920x1080 60 hz at 0x0, DVI-D-0 offset to 1920x0). However, just now, turning the AV receiver & TV on resulted in: VGA-0 on, 1024x768 at 2944x0; HDMI-0 on, 1920x1080 60 hz at 0x0; DVI-D-0 on, 1920x1080 at 1920x0. However, just running 'xrandr > xrandr.output3' (i.e., just outputting the current xrandr state to a text file) caused the monitors to reset to the correct values (although 'xrandr.output3' still showed the incorrect values). Running 'xrandr' again showed the correct values. I will try to install the latest upstream kernel this weekend and see if that makes any difference. ** Attachment added: "xrandr output after turning HDMI accessories back on (failed to restore previous settings)" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1787861/+attachment/5178982/+files/xrandr.output3 -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1787861 Title: Displays not detected/positioned correctly when disconnected/reconnected Status in linux package in Ubuntu: Incomplete Bug description: I just upgraded from Ubuntu 16.04 LTS to 18.04 LTS.

[Kernel-packages] [Bug 1787861] Re: Displays not detected/positioned correctly when disconnected/reconnected
Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.18 kernel[0]. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. Once testing of the upstream kernel is complete, please mark this bug as "Confirmed". Thanks in advance.
