I installed Zorin os on my laptop and after successfully booting first time the screen sort of glitched and wouldn't respond so I force shutdowned it and rebooted and ever since nothing displays on the laptop screen. I did connect it to a external monitor but after booting it shows a pixelated output like this
Any help would be appreciated also I have a amd graphics card [amd mobility radeon hd 5000 series ]
That's one of the notorious video card in Linux. Can you get in TTY/CLI? (where you type commands?
Yes I can get to cli from a second monitor.
Try first something simple by getting all the updates and see if it solved the problem
sudo apt update && sudo apt upgrade
reboot
We also need out put of this:
sudo apt install inxi && inxi -GI can't use network through cli even after using that use network option
Oh ... okay.
lspci -nn | grep -E 'VGA|Display'okay, lets see which driver it uses;
sudo lshw -c videoBTW no display on laptop screen this is from an external monitor
Letts see the xorg file.
cat /etc/X11/xorg.conf
we may switch driver for your card to vesa or something.
Also I booted from recovery mode or else I get that pixelated screen
okay.
sudo nano /etc/modprobe.d/blacklist-radeon.conf
add: blacklist radeon
save - ctrl+o
exit - ctrl+x
reboot
Then:
``
lspci -k|egrep 'VGA|in use'
cat /etc/modprobe.d/blacklist-radeon.conf
cat /etc/modprobe.d/blacklist-framebuffer.confBy the way. Are you sure that the laptop screen isn't broken?
I'm offline, but I'll be back.
No after I first booted after installation then nothing comes on screen not even bios flash
