#debian package source Downgrade the current kernel to the kernel available in stable Running sudo apt edit-sources

Add the stable repository:

deb http://http.debian.net/debian/ stable main contrib non-free Only apt pin the kernel to stable To prevent other packages downgrading to stable, we will only pin the kernel to the stable branch.

Create a new file /etc/apt/preferences.d/kernel with:

Package: linux-image-amd64 Pin: release a=stable Pin-Priority: 950

Package: linux-headers-amd64 Pin: release a=stable Pin-Priority: 950

and /etc/apt/preferences.d/apt-branches with:

Package: * Pin: release a=testing Pin-Priority: 650

Package: * Pin: release a=stable Pin-Priority: 600 For Debian to recognize the repositories, we will need to refresh the package list:

sudo apt update Once this is done, the kernel and headers in stable can be installed:

sudo apt install linux-image-amd64/stable linux-headers-amd64/stable

#debian_extras sudo apt install ttf-mscorefonts-installer rar unrar libavcodec-extra gstreamer1.0-libav gstreamer1.0-plugins-ugly gstreamer1.0-vaapi

#prime I have been plowing the internet for days over this issue. Had similar setup and problems. I chanced upon here about using DRI_PRIME=1 before any commands to use your dedicated GPU. So I tried export $DRI_PRIME=1

and this worked. So I added a line it in /etc/environment, DRI_PRIME=1 , rebooted and now System Details shows my AMD card as default. Caveat: I think this disables the Integrated Graphics and changes your system to just make use your dedicated GPU only

#debian contrib nonfree repos As root you need to edit sudo nano /etc/apt/sources.list Then add contrib and non-free at the end of each line that begins with deb and deb-src just like the example: deb http://http.us.debian.org/debian RELEASE main contrib non-free deb http://security.debian.org RELEASE/updates main contrib non-free Save the file, and run ‘apt-get update‘ and optionally ‘apt-get upgrade‘ to activate the changes. #xanmod custom kernel DEIBAN & DEBIAN BASED echo 'deb http://deb.xanmod.org releases main' | sudo tee /etc/apt/sources.list.d/xanmod-kernel.list && wget -qO - https://dl.xanmod.org/gpg.key | sudo apt-key add - sudo apt update && sudo apt install linux-xanmod #swapcheck On Ubuntu 18.04 you can uninstall btrfs-support with #TIMESHIFT DEPENDS DONT RECOMMEND IT apt purge btrfs-progs But that probably wouldn't save you much boot time. On my system the reason was, that I don't have a swap partition but on boot it is searched for such for about 30 seconds (while displaying the btrfs-scan). #remove the swap check open /etc/initramfs-tools/conf.d/resume replace RESUME=UUID=xxx with RESUME=none issue sudo update-initramfs -u reboot your system source: https://askubuntu.com/a/1034952/34298

#wait online

Use

systemctl disable systemd-networkd-wait-online.service

to disable the wait-online service to prevent the system from waiting on a network connection, and use

systemctl mask systemd-networkd-wait-online.service

to prevent the service from starting if requested by another service (the service is symlinked to /dev/null).

#silentboot

You would need to edit the file /etc/default/grub. In this file you'll find an entry called GRUB_CMDLINE_LINUX_DEFAULT. This entry must be edited to control the display of the splash screen.

The presence of the word splash in this entry enables the splash screen, with condensed text output. Adding quiet as well, results in just the splash screen; which is the default for the desktop edition since 10.04 (Lucid Lynx). In order to enable the "normal" text start up, you would remove both of these.

So, the default for the desktop, (i.e. splash screen only):

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" #Hide text and show splash For the traditional, text display:

GRUB_CMDLINE_LINUX_DEFAULT= #Show text but not the splash For the splash, but the ability to show the boot messages by pressing Esc:

GRUB_CMDLINE_LINUX_DEFAULT="splash" Or, finally, for just a (usually) black screen, try:

GRUB_CMDLINE_LINUX_DEFAULT=quiet #Don't show Ubuntu bootup text GRUB_CMDLINE_LINUX="console=tty12" #Don't show kernel text After editing the file, you need to run update-grub.

sudo update-grub

#xcursortheme

sudo update-alternatives --config x-cursor-theme

#Selecting I/O Schedulers Prior to Ubuntu 19.04 with Linux 5.0 or Ubuntu 18.04.3 with Linux 4.15, the multiqueue I/O scheduling was not enabled by default and just the deadline, cfq and noop I/O schedulers were available by default. For Ubuntu 19.10 with Linux 5.0 or Ubuntu 18.04.3 with Linux 5.0 onwards, multiqueue is enabled by default providing the bfq, kyber, mq-deadline and none I/O schedulers. For Ubuntu 19.10 with Linux 5.3 the deadline, cfq and noop I/O schedulers are deprecated. With the Linux 5.0 kernels, one can disable these and fall back to the non-multiqueue I/O schedulers using a kernel parameter, for example for SCSI devices one can use: scsi_mod.use_blk_mq=0 ..add this to the GRUB_CMDLINE_LINUX_DEFAULT string in /etc/default/grub and run sudo update-grub to enable this option. Changing an I/O scheduler is performed on a per block device basis. For example, for non-multi queue device /dev/sda one can see the current I/O schedulers available using the following: cat /sys/block/sda/queue/scheduler noop deadline [cfq] to change this to deadline use: echo "deadline" | sudo tee /sys/block/sda/queue/scheduler For multiqueue devices the default will show: cat /sys/block/sda/queue/scheduler [mq-deadline] none To use kyber, install the module: sudo modprobe kyber-iosched cat /sys/block/sda/queue/scheduler [mq-deadline] kyber none and enable it: echo "kyber" | sudo tee /sys/block/sda/queue/scheduler To use bfq, install the module: sudo modprobe bfq cat /sys/block/sda/queue/scheduler [mq-deadline] kyber none and enable it: echo "bfq" | sudo tee /sys/block/sda/queue/scheduler

#powerkey ignore

/etc/systemd/logind.conf to disable the power button: HandlePowerKey=ignore To pick up the new setting, restart logind with sudo systemctl restart systemd-logind #mint panel reset

1. Open up your terminal (ctrl+alt+t)
2. Run the following command in the terminal: gsettings reset-recursively org.cinnamon (THIS IS FOR CINNAMON) gsettings reset-recursively org.mate.panel (THIS IS FOR MATE)
