How do I get 1280x1024 resolution?

I'm coming back to lubuntu after a few years. I'm on an AMD Athlon x64 with 2.75 GB ram. I have installed lubuntu 18.04 Alternate 64-bit. I also tried the 18.04 Desktop 64-bit.

A few years ago, I was able to get 1280x1024 res (on a different computer), but not this time. For now, I would even be happy with a command that I have to enter each time I boot. I know the monitor can handle 1280x1024.

Any help appreciated. Otherwise, everything is great.

$ xrandr Screen 0: minimum 320 x 200, current 1024 x 768, maximum 4096 x 4096 VGA-1 connected primary 1024x768+0+0 (normal left inverted right x axis y axis) 0mm x 0mm 1024x768 60.00* 800x600 60.32 56.25 848x480 60.00 640x480 59.94 

Here's all I know at this point:

*-display description: VGA compatible controller product: C61 [GeForce 6150SE nForce 430] vendor: NVIDIA Corporation physical id: d bus info: pci@0000:00:0d.0 version: a2 width: 64 bits clock: 66MHz capabilities: pm msi vga_controller bus_master cap_list rom configuration: driver=nouveau latency=0 resources: irq:23 memory:fd000000-fdffffff memory:d0000000-dfffffff memory:fc000000-fcffffff memory:c0000-dffff 

This works for me but must be re-entered after each boot.

xrandr --newmode "1280x1024_60.00" 108.88 1280 1360 1496 1712 1024 1025 1028 1060 -HSync +Vsync xrandr --addmode VGA-1 1280x1024_60.00 xrandr --output VGA-1 --mode 1280x1024_60.00
