After the Fashionable GNOME Forty update I'm unable to use my second monitor, which happens to be AW2518HF (1920x1080, 240Hz). When I start the PC with the DP cable plugged in, everything's black. If I start the PC without it, it runs as expected. When I plug in the monitor while Solus is running, the primary display freezes and the second display says that there's no signal coming in.
Oh I just read your post again and you say you are. Yes, try to use HDMI if you can. I walked someone in IRC through reinstalling the previous driver but it's a bit tricky because there are multiple packages to downgrade and due to dependencies and reverse dependencies there are going to be at at least one additional package that needs to be downgraded (Linux-current) and likely a few more if you have other things that provide kernel modules installed
@szmarczak Thanks for the details. I'll monitor that thread. Unfortunately while at first people said that 465.31 fixed their issue it seems they were mistaken. If more people are affected by this maybe we should roll the update back, but on the other hand a lot of other issues were fixed in those releases.
I tried plugging HDMI but no luck. The driver still crashed. After that I wanted to plug only one DP cable, but nope - it crashed permanently. But I'm able to access other TTYs on previous kernel.
For what it's worth, I have experienced this issue too whenever I have had to set up my triple monitor setup. Generally works fine if I gradually add monitors to my configuration then export the xorg config to the appropriate location. But regardless, not a Solus-specific issue and thus marking as inavlid.
Glad they are finally fixing it.
Nvidia driver updates tend to get approved pretty quickly, so likely this will be available on stable during the next sync (which happens around Friday). Note that that's just an estimate and if there are any issues with this driver update then it will likely be delayed.
