22.04 Second GPU screens won’t show desktop

hm flag

I just installed Ubuntu 22.04 on my old Windows machine (not dual booting). I have two video cards and four monitors. When I did the installation, all four screens worked correctly. When it’s booting, all four screens work. The GTX 980 is working fine. The GT 730 is detected and the monitors have a signal, but the screens are black. I can move my mouse pointer onto those screens and the pointer icon looks fine, but nothing else will display on the screens. Any idea how I can fix this?

If anyone else runs into this problem, switch from Wayland to X11. To permanently do that: Edit the /etc/gdm3/custom.conf file and uncomment WaylandEnable=false

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
