@yves2 Oh boy you've certainly been on a journey!
I fished out a spare SSD & thought I'd have a go on installing Budgie 4.9 on my Intel i7 6700k & Nvidia GTX 980 system from what I set out before & from reading all the posts afterwards. This is an addendum from my previous post, here's how I got it to work;
- Installed Budgie 4.9 from the live Solus Budgie to my target drive
- Boot into the installed Solus Budgie & update via terminal
sudo eopkg ur & sudo eopkg up
- Reboot to ensure no issues logging in with the updates, installed Solseek & used it to install the Nvidia proprietary drivers
- Rebooted back into motherboard BIOS & selected back my primary display to its previous setting to load from my Nvidia GFX card. Save & shutdown
- Physically swap back the HDMI/DP cable from the motherboard HDMI/DP port to the Nvidia GFX card
- Rebooted & it went to black screen!!! - No problem went into TTY via CTRL+ALT+F3 & ran
sudo usysconf run -f to force all triggers & rebooted
- Voilà! Logged into Budgie 4.9 updated & installed with Nvidia proprietary drivers all good & working on a Intel i7 6700k & Nvidia GTX 980 system
Post Notes
Wasn't sure about Discover for installing drivers since the consensus seems to be its not great at it. I'll trust the community on this hence installed Nvidia drivers via Solseek
The nvidia-glx-driver-32bit I suppose is optional as a fallback for any applications that requires it (mainly for gaming by the looks of it) so I didn't intall it this time round as it was a test. And nvidia-glx-driver-modaliases seems to be for the software center (Discover/Gnome) detection
The installed Nvidia driver packages via Solseek are; nvidia-glx-driver-common nvidia-glx-driver-current
When I hit the black screen, didn't need to sudo eopkg up as system was already up-to-date. Also thinking about it now, after I installed the Nvidia drivers via Solseek. I could have gone into the terminal and ran sudo usysconf run -f before rebooting & swapping the dislay cable?
Just from wading through the forum/github there seems to be issues with Budgie, pre-RTX Nvidia proprietary drivers & lightDM?
I'm sure its an absolute ball-ache for our Solus/Budgie team to work through these Nvidia proprietary drivers - but keep at it guys your doing stellar work!
Just some pointers @yves2 if you ever want to try Budgie in the future
