Acer Aspire TC-780
Intel i5 7400
Radeon R7 250
I can run Manjaro from the USB stick or installed on the HD without issue, until I update the 400+ programs. After updating, both with pacman and the gui package manager, everything functions perfectly until I reboot. After a reboot my computer will freeze a few seconds after logging in or even before if I'm not quick enough. Sometimes I can move the mouse cursor around but nothing responds to clicks. No response to the keyboard at all after the freeze, I have to hold the power button down to turn off my computer. Both monitors will either remain frozen or alternate blinking the frozen graphics and a black screen.
I've tried using 3 different kernels and all have allowed me to reboot and use the computer until I do the full update and reboot. I've tried both XFCE and Gnome and both have the same problem.
I had ran Manjaro on this computer since 2017, without issue, and opted for a fresh install because I hadn't used it for about 6-7 months.
I'm at my wit's end with this, any suggestions?
