[resolved] Zorin OS 12.3 partial display black

[resolved] Zorin OS 12.3 partial display black

Postby lukas21 » Wed Jun 13, 2018 4:53 pm

After update from Linux 4.8.0-54 to Linux 4.13.0-45 I have 3/4 of my display black.
Desktop is present, but can not see it at all. I´m able to login, but this make not change.
If boot from Zorin advanced option to previous version Linux 4.8.0-54, desktop displays correctly.
If connect external display via VGA, desktop is in latest version Linux 4.13.0-45 displayed correctly on it too.
Have dualboot with Win10 and Win XP, both displays normally too.
Internal display resolution is 1024 x 600, Acer One AO51h, Intel Atom dual Core CPU, 2GB RAM.
Can You point me to correct settings, please ?
Thanks, Lukas

Hi

did you got the highest kernel number via the Software Updater in the menu? or have you used an external program like UKUU?

if you return via the boot up to the lowest linux kernel number is your screen issue then solved?
I am confused as Ultimate version 12.2 is running with Zorin 12.2 ultimate running kernel 4.10.0.42.46

kindly let know.

Hi,
via built in "Software Updater".
If I boot Linux 4.8.0-54-generic, have no screen issue, all is displayed correctly.
May be wrong my Software and Updates settings was not "Main server", but server for my country = cz.archive.ubuntu.com ?
Thanks
Lukas

Hi Lukas

thanks for your advice - Swarfendor always is pointing out to use 'main server' for updatings.
I would suggest to stick to 4.08.54.

mind that the small updates you see on kernel versions only involve patching up some issues (and causing others)

within a few months a fresh Zorin OS will come to birth based on Ubuntu 18.04

cheers
