I’m not an enormously knowledgeable linux user (although I’ve used it for quite a number of years now) and I’m an Arch newbie.
I installed Antegros with Gnome 3, and everything seemed to go smoothly until I rebooted. Basic startup seemed to happen OK, but on loading the graphical desktop I was just greeted with a blank screen, no cursor, no nothing. Ctrl-Alt-F2 got me a TTY, however, and there didn’t seem to be anything obviously incriminating in the lightdm logs - lightdm had started successfully; and I didn’t see anything obvious in the X logs either.
After reading a few posts online, I tried switching to GDM, and this seemed to work ok, so I left it at that. Unfortunately, after a while I came to realise how much I dislike Gnome 3, particularly on Wayland, and wanted to switch back to Cinnamon (I was a Mint user before). This is when the wheels started to fall off. I tried using pacman to get rid of gnome and install Cinnamon, but all I ended up with was some sort of butchered gnome with no apps. It seemed like perhaps it was gdm that was causing the problem, so I tried switching out for lightdm, but I got the black screen again.
At this point I decided to start afresh and reinstall, selecting Cinnamon from the beginning. Black screen on bootup. Sigh. Installed gdm, disabled lightdm, enabled gdm - back to the sort of “butchered gnome install” instead of Cinnamon.
More reading; switched to nouveau. Ok, now I have a system that boots with lightdm into Cinnamon: progress - I now know that the problem is some relationship between lightdm and nvidia. But nouveau is too slow for me - I want the proprietary driver, so I need to fix it.
Since then I’ve tried blacklisting the intel driver in /etc/modprobe.d/blacklist.conf, adding rcutree.rcu_idle_gp_delay=1, and adding the nvidia module to the mkinitcpio config file. None of these has made any obvious difference - I still get the same black screen on startup.
For reference, the system is Lenovo Thinkpad T440p with a NVIDIA Corporation GK208M [GeForce GT 730M] and Intel Corporation 4th Gen Core Processor Integrated Graphics Controller.
I’m guessing that people are going to need logs and the output of some debug commands to help, but I’m a bit clueless at this level (I’ve never really understood X properly I’m afraid) so rather than guessing I’ll wait and then provide what people ask for.
Thanks in advance for any help!
