last slackpkg update stopped dual screen
by however from LinuxQuestions.org on (#5BYET)
hi again,
I have been using kdenlive to do some amatorial video editing and this is my box/screen setup:
a) desktop (Xeon E5 v3, 32GB RAM, NVIDIA GF116 6GB,) is connected to two 43" samsung (one LCD and one LED) screens
b) 17" laptop (i7 quad-core, 16GB, nVidia quadro 1G) is connected to a 24" samsung LCD screen
I run slackpkg update on both boxes almost at the same time and when i restarted them (i know it's not necessary but, i like to restart the system after a kernel upgrade)
1) the laptop did not start the 2nd screen at all and kept on freezing almost immediately
2) the desktop has one screen (the secondary) flickering continuously and after about 15-20mins slackware kinda freezes (cant use the mouse and or the keyboard and have to do a hard-reset).
Initially i thought that perhaps the new kernel was too much to handle for the laptop and even doubted that the integrated VGA was completely melted; then the problem seemed to affect also the desktop and I thought that it was too much of a coincidence for a kernel to mess up two completely different sets of hardware so, it has to do with the plasma update of Mon 21st of Dec 2020.
The interesting part is that if I physically disconnect the second screen on both computers it seems to work ok (no flickering, no system freeze).
Anyone has a similar issue? or an explanation and/or a solution?
p.s.: the primary screen on the desktop just started flickering too as i was typing this post; i am guessing that in about 10-15mins i will be unable to use it all and need to restart it
