Has anybody been able to install the NVidia 340.108 video driver in Debian 12?
The messages I found said "Support for it ended in 2019. Use nouveau." But I seem to have trouble with nouveau. When I was running Debian 10 on a Dell Vostro 1700 laptop with NVidia GeForce 8400M graphics, I had been able to install the driver, and had no trouble. I made the mistake of installing Debian 12.5 on the same partition, so I don't have the Debian 10 install anymore. It freezes so completely that the keyboard doesn't work, so I can't switch to a TTY screen. Even if I "ssh" to it from my desktop, I can't kill and restart the graphics. I have a script to restart KDE, but it does nothing. Even "init 3" doesn't do the trick. I have to hold down the power key to reboot. I don't think it's a hardware problem that amazingly manifested simultaneously with a new install. Here's some too-late advice I've given to myself: Never blow away your old install that appears to be working. If you don't have a new disk, and you have room on the old one, make new boot and root partitions. Mark only the new boot partition as the bootable one. Hook both boot partitions to grub.
