If I boot with the VGA cable I can then switch to the VGA/HDMI/DVI cable and everything is still good. But if I restart and boot with VGA/HDMI/DVI I can as most get 1024x768. There must be a way to force Debian to output 1280x1024. I know it can work since It does if I switch the cable after boot.
GRUB_GFXMODE does not work, the screen is black during boot and wakes up at login with 1024x768. vga=794 shows sporadic text during boot, probably at 1280x1024 but goes black and changes to 1024x768 before login. VGA is flawless with the attached grub file. It feels like there is an auto sensing of the screen that sets the correct or wrong resolution after GRUB.
It seems I must use nomodeset to force the VESA driver because with the intel driver my USB mouse does not work with either cable.
Below are INXI and xrandr outputs and the GRUB file.
