The full version of Linux Mint 21 has been published !!!
Linux Mint has published their BETA for 2022. It' s based on Ubuntu's 22.04 release earlier this year. Here I'll have a first look on Mint's MATE edition and how it fares on a LENOVO LEGION 5 box. Overall it seems to work fairly fine. More details below.
INSTALLATION
==========
Boot/Start worked
NO Option to NOT install SWAP partition in standard menu (workaround later in fstab not to boot via #)
Last step before install NOT logical
(after hitting "Install NOW" shows option on which disk to install, BUT NO such option for boot loader, overwrites grub from other mint install)
BT works (Mouse found & connected)
LAN worked
DARK Mode worked
Welcome Screen did not pop up
Font size (10) too small
Brightness worked
Installation completed, Reboot worked & System ready for further adjustments
SYSTEM
======
- OLD mount problem of secondary Linux Mint install still exists (no access, mount crashes), Access to Ubuntu MATE, Manjarao and ARCH work fine.
- OLD ZOMBIE process from Mint menu (Search Internet option) persists
- Direct bitlocker access works, B U T cannot handle autologin for more than 2 different passwords - lol (requires manual login)
- FIREFOX should be REPLACED by LIBREWOLF (has better default PRIVACY settings) OR at least as an option durind installation.
- BOOT space problem solved?? Lack of space after installation of more than 3 Kernels (requires manual deinstallation) --- WHY not increase BOOT partition to 2GB???
nvidia 5.15 driver - works
extreme-cooling.deb - works
updates - works
restart - works
USB Filetransfer
... gets stuck (hangs up) - NOT solved !!!This workaround may helped a little on my Mint system Open a terminal and use xed text editor with root permission, type:
sudo nano /etc/sysctl.d/*99-sysctl.conf
Introduce your password
Scroll to the end of the file and paste :
vm.dirty_bytes=50331648
vm.dirty_background_bytes=16777216
at the and of it, press ctrl-S to save and then ctrl-X to quit xed
Check with sudo sysctl -p in terminal and do a sudo update-grub
O R
vm.dirty_background_ratio = 5
vm.dirty_ratio = 10
In terminal check with sudo sysctl -a | grep dirty
O R
sudo vm.dirty_background_ratio = 3
sudo xed /etc/sysctl.conf

As far as the swap partition goes, you have the option during the install process to install like a “DILETTANTE” (just let the installer decide and partition for you), or you can choose to install like a PRO, via the “SOMETHING ELSE OPTION”.
That way you can partition the Hard Drive(s) – physical or virtual as the case may be – which ever way you see fit, and either include a swap partition or don’t.
I always partition as such:
GPT Partition Table
For a dual hard drive setup (2 physical Hard Drives in the box):
On DRIVE 1:
512 MiB for the EFI – Boot partition
At least 30 GiB for the ROOT (“/”) OS partition, if I install a multi-boot machine, with multiple Linux Distros.
Or, the remainder of the space on the 1st Hard Drive for the ROOT (“/”) OS partition, if I install a single Distro machine.
For a 2 hard drive setup, on DRIVE 2:
A 8,192 MiB (8 GB) partition for SWAP
The remainder of the space on 2nd Hard Drive for the USER HOME (“/home”) partition.
Of course, for a single drive setup, such as the case is on most laptops, I put all 4 partitions on the one and only available physical Hard Drive.
NOTE: I always leave a 1 to 2 GiB unused at the end of each drive, for things like SSD Trim and other hardware specific usage…
Can someone pls. verify this?

Make USB Flash Write Fast Again
I have a 64GB SanDisk Extreme USB flash drive that I use for just about anything. It is a USB 3.0 drive and at the time of purchase, it had the best performance out of all drives in the market.
I can’t remember how fast it was exactly when I first bought it but I remember the read speed was above 200 MB/s and write was above 150 MB/s. But yesterday, a year or so after purchase, I had write speeds of 20 MB/s sometimes falling to 6 MB/s. I wasn’t surprised as I knew at some point all the blocks will be written to and due to lack of support for TRIM, things will get slow — didn’t think that slow!
How do I know it doesn’t support TRIM? If I format and mount an FS with discard mount option and subsequently run fstrim /mnt where /mnt is the mount point of the volume, I get this:
fstrim: /mnt: the discard operation is not supported
OK, but not all hope is lost. I knew about ATA Secure Erase command. What if that works? Turns out it does and it works so well. I followed the kernel guide but here is a summary of commands I ran (change /dev/X to appropriate dev) for the impatient. I strongly recommend reading the full guide.
WARNING as the name suggests, Secure Erase will delete all your data so be sure to make a backup first
Set a user password (Nine is an example, you could use anything):
hdparm --user-master u --security-set-pass Nine /dev/X
Make sure password is set successfully by checking if enabled is shown under Security section:
hdparm -I /dev/X
Run the ATA Secure Erase command — mine took 10 seconds:
hdparm --user-master u --security-erase Nine /dev/X
Verify that security is disabled
hdparm -I /dev/X
After the erase command, I did get an error but it worked nonetheless. Check the before and after graphs of gnome-disk-utility benchmark

ReplyDelete==> Those are the release notes <==
Good to know in case of bugs you may encounter !!!
In case someone encounters same problem in which bluetooth is NOT auto-started after installation of Mint MATE. Simply do this using the command prompt aka bash:
ReplyDeletesudo systemctl enable --now bluetooth.service
