After the xorg server update, which screws up the gpu priority, I decided to install KDE by using plasma-meta package (later by plasma group), then nuked XFCE4 by using “sudo pacman -Rnsc XFCE4 XFCE4-Goodies” followed by “sudo pacman -Rnsc lightdm” So far it works okay, until I get crashes when trying to use edit mode and waking up the display from standby. I dunno if I nuke the XFCE4 de right, or if I made a mistake by installing sudo pacman -S plasma after installing plasma-meta". This is happened on Wayland session, I couldn’t test the X11 session because of the xorg bug which makes the windows animations at 60hz but main monitor is set to 144hz (secondary monitor at 60hz) (Yes, I’m using the dgpu + igpu setup 4790k + gtx 1070 ti). So, do I need to reinstall cachyos to fix this or is there something else to try? Offtopic: How can I prevent the cursor not to be in second monitor after waking up display from standby?

I haven’t tried out x11 because of the xorg update which makes igpu the top priority over dgpu.

I still have a timeshift snapshot on 10/26 that is still on XFCE before the xorg update if no solution ever worked. I should’ve downgraded the 10/28 xorg-server update. :stuck_out_tongue:
