Nvidia driver messes up screen resolution for X11

[joneall]

Thanks for your reply. However, I don't understand, because 375 is what I installed.

$ dpkg -l nvidia-361
dpkg-query: no packages found matching nvidia-361
$ dpkg -l nvidia-375

ii nvidia-375 375.39-0ubuntu0. amd64 NVIDIA binary driver - version 375.39

Why is xorg.conf still talking about 361?

Hi,

you should be using the "nvidia-375" package according to the Nvidia drivers website!, (see supported products):

http://www.geforce.com/drivers/results/114708

If you can get into recovery mode (a network cable connection is required!), first go to "network" and then "root" and enter the following command:

sudo apt-get remove nvidia-361 && sudo apt-get install nvidia-375

Restart with Ctrl + Alt + Del, do not click on resume!.

I tried checking

Force fonts DPI 96

in system settings > fonts. The fonts are almost normal now, but the login screen is still a mess, so that is not the best solution. Plus, in Konsole, my cursor is 3 steps ahead of what I type, by which I mean that there are three blanks at the end of the line before the cursor, which is really weird. Makes it practically impossible to backspace and correct typos.

I may have to remove nvidia and go back to occasional crashes (nouveau 0000:01:00.0: fifo: SCHED_ERROR 0a [CTXSW_TIMEOUT]).

I installed the Nvidia driver under Neon.

Now I have a real mess. It's as if the screen resolution were on some very low value. If I look in system settings or the nvidia conf editor, it says 1920x1200, which is correct. But all the windows are huge as are the characters on the bars above them. Curiously, tho, this page on Firefox looks fine, except for the X11-generated window bar at the top. Thunderbird, tho, looks like ... garbage, as does Chrome.

I tried deleting /etc/X11/xorg.conf and rebooting, but the system did not even build a new one and the problem persists.

The system is unusable in this state. Any urgent help appreciated.

Here's the contents of xorg.conf, if that is any help:

I'm running KDE neon LTS 5.8 with an Nvidia GK107 [GeForce GT 740] graphics card.

I originally posted this under a different title, then moved it here. Sorry for any confusion.
