Public bug reported:
I just installed ubuntu 23.10 on my thinkpad L13. It works fine on my
laptop monitor. But when I connect an HDMI cable to my other monitor,
then the screen flickers on the laptop and nothing shows on the other
monitor
I know it can't be the problem with the other monitor as I bought it
brand new last week, and the cable works fine on this same laptop when I
run in windows, and it works fine on other laptops with windows/mac
I already installed the driver with `sudo apt install nvidia-driver-535
nvidia-dkms-535` and rebooted, but that didn't help. I then installed
driver 550 and I still have the flickering
This laptop uses an intel Alder Lake-UP3 GT2
I also tried editing `etc/default/grub` by adding 'nomodeset' or
'radeon.modeset=0' within the quotation marks in the line
GRUB_CMDLINE_LINUX_DEFAULT but that didn't help either
can anyone help?
