Thanks for the bug report. The attached Xorg logs appear to be from before the bug as they show a resolution of 1600x900. But I can also see that your current resolution is 800x600 in Xrandr.txt. It seems Xorg now can't even tell what kind of monitor connection it is.

Please try booting an older kernel by accessing the grub menu (press Esc at startup). Do you find older kernel versions avoid the problem?

Please also try unplugging and reconnecting the monitor.

Weirdly, this sounds just like bug 1943239. But the kernel version is different and the GPU type is different.
