Install KDE Plasma on SparkyLinux GameOver 08/11 2020

At the time of writing KDE Plasma install  on any SparkyLinux 2020.09 might be committed via GDM3 installation right after KDE Plasma ( the last one via tasksel or CLI ) due to after system reboot GDM seems to be the only one DM on Sparky detecting previously installed KDE.


Roll forward Sparky Linux up to current repositories state.

1. Run taskel installing 

* Debian Desktop environment

* KDE Plasma

















2. Run

$ sudo apt install gdm3 -y

During installation set gdm3 as default DM . This is the only one DM detecting presence of previously installed KDE Plasma in meantime. Reboot and select option "plasma" via clicking on gear in right down corner of login screen

   Sparky 2020.09 (UEFI mode)  rolled forward all the way through up to the time of writing behaves same way on bare metal .








END UPDATE

Due to Libvirt version 6.8.0 there is no more any problems with deployment KVM Guests on EXT4 file system, compare with http://lxer.com/module/newswire/view/290245/index.html

 Deploy SparkyLinux 2020.9 ( rolled forward up to 11/08/2020 ) as KVM guest on F33 Server as follows

VM has been deployed in legal BIOS mode on EXT4 filesystems

Issue with Btrfs in Libvirt 6.6.0 has been fixed in Libvirt 6.7.0 release.

Bug fixes : Fix logic in setting COW flag on btrfs

When COW is not explicitly requested to be disabled or enabled, then libvirt should do nothing on non-BTRFS file systems.
