https://bugzilla.suse.com/show_bug.cgi?id=1208171 Bug ID: 1208171 Summary: Unable to switch to Nvidia or Intel appropriately on MicroOS Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: x86-64 OS: openSUSE Tumbleweed Status: NEW Severity: Critical Priority: P5 - None Component: MicroOS Assignee: kubic-bugs@opensuse.org Reporter: groguko36@tuta.io QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- I'm using Micro OS Gnome here. I installed the Nvidia G06 driver with `suse-prime` and `bbswitch`. I had trouble with switching graphic cards. According to `prime-select.log', it couldn't detect Intel when I tried to switch to it. Then it would attempt to switch to Nvidia instead and caused black screen with login, because it also couldn't detect Nvidia. Here is the part of the log: ``` [ 18:36:16 ] service restored by user [ 18:38:35 ] user_logout_waiter: started [ 18:38:35 ] user_logout_waiter: X restart detected, preparing switch to intel [ 18:38:35 ] Forcing nvidia due to Intel card not found [ 18:38:35 ] Unloading bbswitch and switching nvidia ON... [ 18:38:38 ] PCI BusID of NVIDIA card could not be detected! [ 18:38:38 ] Configuration failed [ 18:39:42 ] Boot: setting-up card [ 18:39:42 ] HotSwitch: completed! ``` Interestingly, when I switched to Nvidia, `suse-prime` complained about not able to detect Nvidia and wanted to switch to Intel. This time the Intel just mysteriously worked along with bbswitch. ``` [ 20:47:07 ] user_logout_waiter: started [ 20:47:07 ] user_logout_waiter: X restart detected, preparing switch to nvidia [ 20:47:07 ] Forcing intel due to NVIDIA card not found [ 20:47:07 ] NVIDIA card will be switched off, NVIDIA offloading will not be available [ 20:47:07 ] trying switch OFF nvidia: [bbswitch] NVIDIA card is OFF [ 20:47:07 ] Intel card correctly set [ 20:47:07 ] HotSwitch: starting Display Manager [ 20:47:08 ] HotSwitch: completed! ``` I think these are MicroOS exclusive issues, as I never encountered them on Tumbleweed. It's similar to one of the old issues here reported two years ago. Switching to Nvidia G05 driver doesn���t help either. The issue was also reported on the SUSE-Prime's page: By default, MicroOS comes with less installed packages than Tumbleweed, nor does it have ���recommended packages��� like Tumbleweed. For example, my Tumbleweed ships with packages like intel-media-driver intel-vaapi-driver xorg-x11-driver-video libvulkan_intel Mesa-vulkan-device-select, which MicroOS doesn���t. Here I���m wondering if missing driver-related packages are missing might be the cause of the issues mentioned above. Or maybe there is something wrong with detecting graphic card on MicroOS' end. -- You are receiving this mail because: You are the assignee for the bug.
