    Monitor does not wake up after sleep

    I am using kubuntu 20.04. I have an ATI Radeon RX 550 640SP / RX 560/560X. Did not had this problem couple of days ago, appeared suddenly (probably after an update).
    Do you have any ideas?
    Thanks in advance

    Try booting with an older kernel. If it works then the problem is indeed with the current kernel version.

    Thanks!That did the trick!
    Is there a way to fix the issue with the new kernel or should I set default the 5.4.0-29-generic one in grub?
