Testify :(
I'm still struggling to get my (IMHO, extremely vanilla) setup working (Ubuntu on Thinkpad T430 + 2 external QHD monitors), and I'd appreciate any pointers to any resources that can help me resolve this.
- toupeira 7y agohttps://wiki.archlinux.org/index.php/HiDPI https://wiki.archlinux.org/index.php/HiDPI has lots of information. I have a Thinkpad X1C and an external monitor, both with QHD resolution. What I ended up with is using xrandr scaling to increase the resolution of the external monitor (probably should have gotten a 4K instead...), and tweaking font sizes and Firefox's UI scaling until it looks okay on both screens. For QT apps I also had to set QT_AUTO_SCREEN_SCALE_FACTOR=0. Some proprietary apps are still too small though, so I tend not to use them ;-) The xrandr scaling is applied through a script and not persistent, so I mapped it to a keyboard shortcut I can press when I reconnect the monitor. My script looks like this: xrandr \ --output eDP-1 --pos 0x0 --scale 0.9999x0.9999 \ --output DP-2 --pos 2560x0 --scale 1.25x1.25 The silly 0.9999x0.9999 scaling on the first screen is to work around a mouse flickering bug in the modesetting driver: https://gitlab.freedesktop.org/xorg/xserver/issues/70 https://gitlab.freedesktop.org/xorg/xserver/issues/70
- shrikant 7y agoThis looks useful -- thanks! Will try out some of the suggestions mentioned here.
- diffeomorphism 7y agoIs that about weird multistream displayport connections? Two times QHD is definitely not vanilla and was unsupported on windows until a while ago as well.
