Description Petr Vorel 2024-02-19 14:03:18 UTC

Tumbleweed Live DVD (tested on openSUSE-Tumbleweed-KDE-Live-x86_64-Snapshot20240213-Media.iso, but problem was much older versions as well) detects connected external screens thus kscreen_osd_service is started. On my Thinkpad P16 which has problems with external screens setup, therefore whatever I click the dialog pop up again. Even I click "Leave unchanged" icon (on the left), it keeps pop up, which makes whole KDE unusable.

Note: this happens when internal GPU (Intel Corporation Alder Lake-HX GT1 [UHD Graphics 770] (rev 0c)) is disabled in BIOS and there is only NVIDIA GPU enabled:

# lspci |grep VGA
01:00.0 VGA compatible controller: NVIDIA Corporation GA107GLM [RTX A1000 Laptop GPU] (rev a1)

# drm_info |grep Node 
Node: /dev/dri/card0

# ls /dev/dri/card* 
/dev/dri/card0

Shell I report it to upstream (KDE)?

Comment 1 Petr Vorel 2024-03-28 13:03:56 UTC

It looks like it's fixed in openSUSE-Tumbleweed-KDE-Live-x86_64-Snapshot20240326-Media.iso.
