I've installed Debian 10 Buster (10.2 LXDE to be exact but I've also tried Gnome and XCFE) on my latest desktop (HP Pavilion TP01-0012NP) but I can't reach the display manager's login prompt (X doesn't start, I guess). Windows 10 came pre-installed and works fine.
As for Debian, I can log in by going into terminal mode (Ctrl-Alt-F2) but have been unable to fix the problem, which appears to be related with the graphics card (Geforce GTX 1650) driver. I've tried installing the proprietary drivers, including from the buster-backports repository but so far no luck.
running startx from the terminal results in:
xinit: giving up
xinit: unable to connect to x server: connection refused
xinit: server error
The tips provided in other threads (e.g., debian 10 - hybrid graphics - how to use nvidia drivers instead of nouveau) did not get me far. These included: 1) Blacklisting nouveau via the /etc/modprobe.d/ folder; 2) Installing the proprietary driver (from the non-free repositories, standard or backports versions); 3) Running nvidia-xconfig to generate a xorg.conf file and placing it the /usr/share/X11/xorg.conf.d/ folder.
I've tried running a Ubuntu 18.04 live distro and it loads their display manager (unity?) but I get a low resolution so my guess is vesa is being used.
nvidia-detect says I should install nvidia-driver.
I don't think this desktop has a second graphics card (motherboard-based).
What else can I do? Thank you in advance.
FYI, I don't really need the graphics card for gaming or anything very demanding on that front.
