Bug ID: 360417
Summary: Panels, plasmoids and wallpaper disappears when using
a HDMI display splitter
Product: plasmashell
Version: 5.5.5
Platform: openSUSE RPMs
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: Multi-screen support
Assignee: aleix...@kde.org
Reporter: cer...@luukku.com
CC: plasma-b...@kde.org
I'm using laptop with it's own screen turned off and attached to HDMI splitter
where screen is splitted to two displays (can be viewed simultaneously). It's
been working fine until resently. Every now and then Plasma panels, plasmoids
and wallpaper disappears leaving only black screen instead. Everything else
seems to continue working normally. This happens especially when returning from
suspend (output of ~/.Xsession-errors below). Normal behaviour starts after
restarting Plasma.
This behaviour may have been started because I tried to plug an additional VGA
monitor. It worked but sometimes forementioned desktop elements would disappear
from HDMI screen (set as main display) and appear in VGA monitor. So I
unplugged and haven't used VGA monitor since then but got this same kind of
behaviour in HDMI screen also. Software updates may also have an effect (using
rolling release). I've deleted ~/.local/share/kscreen but that didn't help.
I'm using openSUSE Tumbleweed, Plasma 5.5.5, Qt 5.5.1, Frameworks 5.19.0,
kernel 4.4.3. Computer: Dell Latitude E5420. Graphics: Intel HD 3000 (Mobile
Intel HM65 Express -chipset). Open source drivers. HDMI Splitter: Jebsee HD
4200. Both HDMI displays are 1920x1080 resolution and 60hz.
Reproducible: Always
Steps to Reproduce:
1. Use a HDMI splitter and 2 monitors.
2. Start suspend
3. End suspend
Actual Results:
Plasma panels, plasmoids and wallpaper disappear leaving only black screen
instead. Everything else seem to work: mouse, programs, Plasma shortcuts,
screen edge actions, etc.
Expected Results:
Those desktop elements should't disappear.
