I am using XFCE DE. Tried to install Thunar GTK3 and Thunar was removed. Now i cannot login to Manjaro. The welcome screen will come back again. Several error messages like the following appear on the screen:
43.783868] [drm:drm_atomic_helper_comit_cleanup_done [drm_kms_helper]] ERROR [CTRC:32:pipe A] flip_done timed out
how should I login to Manjaro and correct the Error?
Probably other gtk3 packages were also installed alongside thunar-gtk3 and other conflicting gtk2 packages removed, and since gtk3 is not really stable yet, this is what could have caused your issue.
Follow this guide to login to tty terminal, then remove thunar-gtk3 and install thunar, this will probably reinstall the previously removed gtk2 packages as well. If not, check in /var/log/pacman.log which packages (if any) were removed when you installed thunar-gtk3 and reinstall them manually.
To install thunar-gtk2 from the tty, which will also remove thunar-gtk3
Thank you so much for your prompt response and clear guide.
So far I was able to replace Thunar gtk3 with Thunar in tty and rebooted but the problem is still there. Am going to the next step to search manually. I will report the result here soon.
Thank you. I did that and indeed several gtk3 packages were removed. but at the end it says : failed to prepare transactions (could not satisfy dependencies. i am going to reboot anyways to see what will happen.
Still no success. What if I do the first steps of replacing thunar with thunar gtk3 on my another Manjaro computer to find out which files will be replaced and the correct those in the affected computer?
