Hello there,
My problem is that after latest kernel update (6.5 to 6.8) my display randomly switch black about 1-2 sec.
My device a HP Elitebook 840 G3. I use it with a Dell External monitor, with Displayport output.
i found these problem on ubuntu forum:
Yes, this Kernel makes here Issues, too. Are You using a Nvidia Graphic in Your Machine? Did You tried to go back to the 6.5 Kernel and use it?
No, i use Intel graphics. I dont try to revert kernel update, but it working without issue with 6.5 kernel before i update it.
You can select and boot a previous kernel generic (e.g. 6.5.*) by choosing "Advanced Options for Zorin" on the grub menu at startup. See if that helps. If so there are ways to hold onto that working kernel for now.
You don't need to revert the Kernel Update. Like @zabadabadoo wrote and explained, you can go to the GRUB Menu and chose there the older Kernel.
And when you want keep the Kernel, You could use this Guide:
I do some test, and seems it fixed the 6.10 kernel. i use Zabbly kernel.
Details:
Revert to 6.5 is also help.
it also fix it on 6.8 kernel:
Adding intel_iommu=igfx_off to /etc/default/grub resolved the issue for me too.
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash intel_iommu=igfx_off"
