Hello,
I’ m new Manjaro user and I have been using it for a few months. Anyway yesterday I did a big system update (20.1 i guess) and then shut down my computer. Today, in morning I turned on my computer and I have received this message:
[FAILED]Failed to start **Light Display Manager**
So I start googling, how to solve this problem and I found a solution on this forum: https://forum.manjaro.org/t/failed-to-start-light-display-manager-after-update/23449
But I but i can’t get to shell after rebooting. CTR+ALT+F1,F2… etc. doesnt working. Please advise me how to solve this problem then I’ll try it fix it myself what I found here on the forum. Thanks a lot.
Try to boot in text mode instead of graphical mode ones
set multi-user-target for only one boot in grub.
Push “e” in your grub menu and change the linux line (the line that includes vmlinux). At the end you need to put “3” after that start grub with “ctrl+x” and you should be staring in text mode instead of graphical.
Change what you have to change and reboot “systemctl reboot” to reboot in graphical mode.
Thanks for respond SLaItEr, I did what you wrote me and you think this line, right?
linux /boot/vmlinuz-5.8-x86_64 root=UUID=cf8ceb8d-e08e-40c0-b0b0-1d55bf954854 rw quiet apparmor=1 security=apparmor udev.log_priority=3
Well it was set already with “3” on end of line. After that I press CTRL+X it appears “^X”, it is text mode? I sorry for me, but I’m still new and have big difficulties with Linux.
Are you using an Nvidia GPU and do you have cuda installed? If so uninstall cuda I had a similar problem and actually reverted to the previous driver but now I got the current one installed the difference was that I had to uninstall cuda.
Assuming I was correct about the above to the following.
Once you get past the Manjaro boot menu press Ctrl+alt+F3 to get too try
Then run mhwd -r video-nvidia-440xx
Them mhwd -i video-nvidia-450xx and sudo pacman -S video-nvidia-450xx-utils
Then reboot
I may be a little off on the exact package names I’m trying to remember them for memory but hopefully that is correct.
I know that, recently I read your post and I planning make exactly what you recommend. But I still cant use text mode and make a next step. Its very frustrating for me, I use Manjaro like normal user. I solve a few problems, because I was easy, but this is a little bit much over me. Yes I have Nvidia GPU and without CUDA, when I solve this problem with LDM I will look at it.
My mistake. Ok, I get into text mode and follow instructions by LinuxLoverForever and install video-linux, then I try uniinstal nvidia drivers, but it end with error.
checking dependencies...
error: failed to prepare transaction (could not satisfy dependencies)
:: removing linux57 breaks dependency 'linux57' required by linux-latest
:: removing linux57-nvidia-340xx breaks dependency 'linux57-nvidia-340xx required by linux-latest-nvidia-340xx
error: pacman failed!
error: script failed!
Ok, I solve it. I use sudo pacman -Rcsnu linux57-nvidia-340xx to erase this package and then mhwd -r pci video-nvidia-340xx to eliminate dependent packages. Now I have only linux video drivers and I’m in system. I want thank you, SLaItEr and LinuxLoverForever for help.
