However a) I want to use KDE, and b) I still haven't managed to get anything graphically interesting to work, i.e. Windows games via Steam, which I have been able to run before now on the IGP. Rebooting with only the AMD card connected to the monitor doesn't work either. I may have to disable the IGP from the BIOS, but I can't believe this is the only solution. poc _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam, report it: https://pagure.io/fedora-infrastructure/new_issue
