Hi, think I have the same issue. First I thought it was related to screen rotation but it turns out that is only partially true: When I connect my screens without kde/plasma in the sddm loginmanager the screens come to live in mirrored mode. This work every time. The screens being connected at boot or not. When I then use xrandr to configure my rotated desktop setup the freeze happens. Well not really a freeze it seems the graphics card simply does not update the screen. Everything still works. The cursor too. I think this is because its a hardware rendered cursor. The only relevant message i could extract from journal/X.org.log etc is this: [drm] Reducing the compressed framebuffer size. This may lead to less power savings than a non-reduced-size. Try to increase stolen memory size if available in BIOS. After seeing this i tried turning off compressed framebuffer by adding i915.enable_fbc=0 to the kernel command line. Now I can attach/detach screens without problems. But the Graphics are very slow. Any Ideas? cheers Wonko On Tuesday, 20 June 2017 10:11:20 CEST Vojtěch Zeisek wrote:
I'm not sure if this issue was caused by this (20170618) or the previous snapshot, but after tomorrow upgrade (I previously upgraded at Friday), I have problem with external monitor. I have VGA compatible controller: Intel Corporation HD Graphics 520 (rev 07) and fully upgraded TW with KDE. If I plug external monitor (HDMI if it matters), the Plasma freezes. Restart of the Plasma doesn't help. It is not possible to click on anything, nothing. Interestingly, unplugging the monitor defreezes everything and the desktop is fully usable again. As a workaround, the monitor must be plugged before turning on of the computer. Then everything works as usually. Anyone else experiencing this?
