Half a Page of Scribbled Linux

When running Meld on macOS Mojave, the Meld window will sometimes fail to appear.  The menu is there, but not the window.  Once this happens, it will stay broken until some saved state files are deleted:
rm -rf ~/Library/Saved\ Application\ State/org.gnome.meld.savedState/

The kludgey fix is to have the Meld start-up script do this for you. Add that line to /usr/local/Caskroom/meld/3.19.2-r6,osx-15/meld.wrapper.sh right before
exec '/Applications/Meld.app/Contents/MacOS/Meld' "$@"

The proprietary NVidia drivers for the GeForce GTX 750 are acting up again. Here’s the fix:

First verify that the wrong driver is in use:

lspci -nnk | grep -iA2 vga

01:00.0 VGA compatible controller [0300]: NVIDIA Corporation GM107 [GeForce GTX 750] [10de:1381] (rev a2) 
    Subsystem: Micro-Star International Co., Ltd. [MSI] GM107 [GeForce GTX 750] [1462:3101]
    Kernel driver in use: nvidia

You should see nvidia as the kernel driver.  If you’re here, you probably see nouveau and maybe a few others.  Nouveau doesn’t work right with the GTX 750 and never has (and probably never will).

Download the NVidia 64-bit Linux driver.  At the time of this writing, it’s at https://www.geforce.com/drivers/results/145182

Install the driver. This is a two step process because the Nouveau driver is likely loaded by initramfs and needs to be removed. This requires a reboot.

sudo service lightdm stop
sudo sh ./NVIDIA*         # This is the driver you just downloaded
sudo update-initramfs -u  # purge nouveau driver from initramfs
sudo reboot

If your graphics are running at the right resolution, you can stop here.  If not, continue:

sudo service lightdm stop
sudo sh ./NVIDIA*
sudo service lightdm start
