New issues:

Compiz packages like compiz-easy-patch got dropped from our repositories. Due to protobuf update you may need to rebuild that package locally on your end. Compiz-easy-patch removed from repos
Some Nvidia cards don’t work with the current 460.80 drivers when used with Display Port and/or 4k Monitors. More about the issue at the Nvidia Developer Forum. We recommend to switch to Nouveau driver as needed. If you however need the Nvidia driver, you can get the PKGBUILDs of the 460.73.01 version and build your driver locally with makepkg or use the pre-compiled packages: nvida-utils, dkms and lib32 + precompiled .

Nvidia card owners

We simplified nVidia driver installation. This means we dropped legacy drivers.
- We recommend to switch over to Nouveau drivers if your card is mentioned here and the feature you need is not in red TO DO here for your particular card.
- If you however still need proprietary drivers, you may want to execute the following to ensure all parts of the nVidia drivers get installed properly:
```
sudo mhwd -a pci nonfree 0300
```
  If proprietary drivers don't fix everything, please click the ► at the beginning of this line to view more info
  1. try installing kernel 5.4 LTS (Long Term Support)
  2. If that doesn’t fix it, take a full system backup, go to a console using Ctrl+Alt+F2 and:
  - Backup /etc/X11/mhwd.d/nvidia.conf if you ever edited that manually
  - remove all nVidia related drivers and applications:
```
pacman --remove nvidia*
```
  - Note which applications are being removed and keep them handy in a list
  - Install the driver first:
```
mhwd --install video-hybrid-XXX-nvidia-prime
```
    (Where XXX is amd or intel if you have hybrid graphics or the whole thing is video-nvidia if you’re on an nVidia-only system)
  - reboot and see if you at least get a screen.
  - Install all the other applications from your handy list that you still need one by one.
  - Restore /etc/X11/mhwd.d/nvidia.conf if you ever edited that manually
  - If that wouldn’t solve the issue open a new issue here referring to this update and posting at a minimum the full output of:
```
inxi --admin --verbosity=7 --filter --no-host --width
```
  If you however still have issues with your Nvidia card, you may open a new thread in our forum: Graphics & Display - Manjaro Linux Forum or look at our tutorial on compiling old Nvidia drivers.

For AMD GPU users having a black screen with kernel 5.10

Please click the ► at the beginning of this line to view more info

Due to a bug in the AMD drivers, please try the following first:

For GRUB:

Open a terminal or a TTY
Open /etc/default/grub in your favourite CLI editor (nano vi, emacs`)
Find the line: GRUB_CMDLINE_LINUX_DEFAULT="
Add amdgpu.dc=0
Save
Execute sudo update-grub and reboot

For systemd-boot:

Open a terminal or a TTY
Open /boot/loader/entries/manjarolinux5.10.conf in your favourite CLI editor (nano vi, emacs`)
Add amdgpu.dc=0 to the end of the line options
Save & reboot

For rEFInd:

Open a terminal or a TTY
Open /boot/refind_linux.conf in your favourite CLI editor (nano vi, emacs`)
Find the line: "Boot using default options" "root=
Add amdgpu.dc=0
Save & reboot

Possible 2 Min delay on shutdown with Gnome

Please click the ► at the beginning of this line to view more info

If you got the problem with shutdown delay (about 2min) on Gnome, here is a workaround:
- Edit /usr/lib/systemd/user/gnome-session-restart-dbus.service in your favourite editor as root and add Slice=-.slice as a line all by itself like this:
```
[Service]
Type=notify
Slice=-.slice
ExecStart=/usr/lib/gnome-session-ctl --restart-dbus
```

Touchpad on a ThinkPad stops working

Restart again, please.

You get `[PKGNAME] warning: directory permissions differ on [Directory name]`

followed by:

Filesystem: NNN package MMM

Please click the ► at the beginning of this line to view this solution

The solution:
```
sudo chmod MMM DirectoryName
```

Where obviously MMM is the second number you see (the correct one)

The explanation:
Your package expects the security permissions to be MMM but your system is set to NNN. This is just a warning (today) but to ensure you remain up-to-date with the latest and greatest security rules it’s advised to execute the above command.

Systemd error message: .slice: Failed to migrate controller cgroups

If you have a similar error message like this:

systemd[1004]: -.slice: Failed to migrate controller cgroups from /user.slice/user-1000.slice/user@1000.service, ignoring: Permission denied

… you may need to add this Grub parameter to your /etc/default/grub file in line GRUB_CMDLINE_LINUX_DEFAULT: systemd.unified_cgroup_hierarchy=true. To update your grub menu, call: sudo update-grub. For more information on that issue, see also Arch Forum.

Python 3.9 Requires Rebuilds

Instructions for quickly and easily rebuilding affected AUR packages:

# Install yay
sudo pacman -S --needed --noconfirm yay

# Rebuild AUR python packages
yay -S --noconfirm $(pacman -Qqo "/usr/lib/python3.8/site-packages")

libtraceevent>=5.9-1 update requires manual intervention

2020-10-23 - Sébastien Luttringer

The libtraceevent package prior to version 5.9-1 was missing a soname link. This has been fixed in 5.9-1, so the upgrade will need to overwrite the untracked files created by ldconfig. If you get any of these errors
libtraceevent: /usr/lib/libtraceevent.so.1 exists in filesystem
when updating, use
pacman -Syu --overwrite /usr/lib/libtraceevent.so.1
to perform the upgrade.

Arch Linux - News: libtraceevent>=5.9-1 update requires manual intervention

OpenVPN connection times out.

Workaround: donwgrade openvpn (2.5.0-1 => 2.4.9-2).
For a proper solution follow this bug report on Arch Linux: FS#68480 : [openvpn] running unprivileged with iproute no longer working

PAM and PAMBASE got updated, which might prevent you from login

Due to updates from pambase and pam you might take care about any .pacnew files in /etc/pam.d as for example pam_tally, pam_tally2 and pam_cracklib got deprecated. Read in the ArchWiki about managing those files.

Typical issue:

For recovery, it is enough to boot with kernel option “systemd.unit=rescue.target”, then proceed into /etc/pam.d and merge “system-auth” and “system-auth.pacnew”

System takes a long time to boot

If you’ve got errors like Failed to start Network Manager Wait Online. you can try removing systemd from passwd and group in /etc/nsswitch.conf as described here
Update: If you can see the line
dbus-daemon[1453]: [system] Connection has not authenticated soon enough, closing it (auth_timeout=30000ms, elapsed: 45146ms)
in in your dbus log ( journalctl -b -u dbus ), the new/better workaround is to switch cups from service to socket as described here:
systemctl disable cups.service
systemctl enable cups.socket

I think I’ve some font problems

With the update of fontconfig some major rules how fonts get applied changed. Make sure that your system has ttf-dejavu installed. A more in depth explanation can be found here.

Gnome-shell-extension-pop-shell is currently incompatible with wayland

… and causes the system to freeze when the first window is tiled and can render it unbootable. Solution is a hard reset and disabling either pop shell or wayland. If the system becomes unbootable, use a live USB to edit /etc/gdm/custom.conf to disable wayland and reboot.

GDM does not start (black screen when booting gnome edition)

Log into your system via tty and depending on your use of Plymouth or bootsplash-systemd choose a option from this post
