zram vs suspend to disk?

Optimize mirrors:

zypper in mirrorsorcerer

sudo mirrorsorcerer -x
systemctl enable --now mirrorsorcerer 

reboot

 Edit zypp.conf:

sudo micro /etc/zypp/zypp.conf 

 

parallel downloads=5

download.min_download_speed = 20000

 

Install opi:

sudo zypper install opi

sudo zypper install -t pattern devel_basis

Install Pycharm:

sudo zypper in libgthread-2_0-0 gcc-fortran gnome-disk-utility texlive

sudo opi pycharm

sudo zypper in python3-pandas python3-suds python3-colorama python3-reportlab python3-svglib

sudo pip3 install chess --break-system-packages

sudo opi micro

 

Rstudio-desktop:

sudo zypper in R-base-devel

sudo opi rstudio-desktop

opi version is outdated, so can also download Opensuse rpm from: https://posit.co/download/rstudio-desktop/ 

then:  sudo zypper in [downloaded rpm file]

You also need to: sudo zypper in openssl-1_1

If you manually install rstudio, zypper will want to downgrade....so run sudo zypper al rstudio.....which locks the package (sudo zypper removelock rstudio to remove lock)

 sudo opi rjava (after installing java-21-openjdk-devel pcre2-devel lzma-sdk-devel libbz2-devel)

OpenRGB:

To install OpenRGB with hardware access on openSUSE Tumbleweed, follow these steps:

1. Install OpenRGB from the official repositories:

```bash
sudo zypper install OpenRGB
```

2. Install the i2c-tools package, which is needed for accessing certain RGB devices:

```bash
sudo zypper install i2c-tools
```

3. Load the necessary kernel modules:

```bash
sudo modprobe i2c-dev
sudo modprobe i2c-piix4  # For AMD systems
# OR
sudo modprobe i2c-i801   # For Intel systems
```

4. To make these modules load automatically on boot, create a new file:

```bash
sudo nano /etc/modules-load.d/openrgb.conf
```

Add the following lines to the file:

```
i2c-dev
i2c-piix4  # For AMD systems
# OR
i2c-i801   # For Intel systems
```

5. Install the OpenRGB kernel patches:

```bash
sudo zypper install i2c-openrgb-kmp-default
```

6. Reboot your system to apply the changes.

7. Run OpenRGB with sudo privileges:

```bash
sudo openrgb
```

If you want to run OpenRGB without sudo, you can add your user to the i2c group:

```bash
sudo usermod -aG i2c $USER
```

Then log out and log back in for the changes to take effect.

sudo zypper ref
sudo zypper install OpenRGB
sudo zypper in i2c-tools
sudo usermod -aG i2c hugh
sudo modprobe i2c-dev
sudo modprobe i2c-piix4
cd /etc/modules-load.d/
sudo touch /etc/modules-load.d/i2c.conf
sudo sh -c 'echo "i2c-dev" >> /etc/modules-load.d/i2c.conf'
sudo sh -c 'echo "i2c-piix4" >> /etc/modules-load.d/i2c.conf'

Fedora Install Notes

 

Many of the steps in setting up Fedora are the same as I do for Arch.  My preferred install is Fedora Rawhide.  You are better off with the default "Gnome" desktop than trying the KDE spin (seems to be the best integrated experience with few/no hardware/GPU issues).

Helpful notes to me:

Initial "get started" installs:

sudo dnf in duf wget fastfetch git btrfs-assistant gnome-disk-utility libcurl-devel java-latest-openjdk-devel freetype-devel libpng-devel libtiff-devel libjpeg-devel fribidi-devel bat micro gnome-tweaks ptyxis gnome-extensions-app python3-ipykernel lftp llvm-devel tcl8-devel tcl8 tk8-devel tk8 python3-pip python3-colorama R fish xsane sqlitebrowser

Snapper:

sudo dnf copr enable kylegospo/grub-btrfs

sudo dnf in grub-btrfs

sudo grub2-mkconfig -o /boot/grub2/grub.cfg

do rollback:

Use sudo snapper ls to list all available snapshots and their corresponding numbers.

Note the number of the snapshot you want to revert to.

Open a terminal and use the following command: sudo snapper rollback <snapshot_number>.

Replace <snapshot_number> with the actual number of the snapshot you want to rollback to.

You might need to use the --ambit option with the classic value if you encounter an error about an unknown default volume. The command would then be for example: sudo snapper --ambit classic rollback 5

After the rollback is complete, reboot your system to boot into the restored state.

On the boot screen, choose the default boot entry to reboot into the reinstated system.

A snapshot of the file system status before the rollback is created.

The default subvolume for root will be replaced with a fresh read-write snapshot.

Microsoft Edge:

sudo rpm --import https://packages.microsoft.com/keys/microsoft.asc
sudo dnf config-manager addrepo --set=baseurl=https://packages.microsoft.com/yumrepos/edge
sudo dnf in microsoft-edge-beta




Rstudio:
download nightly build for Fedora and then sudo dnf install xxxx.rpm from Downloads directory

Onedrive:
sudo dnf in onedrive

eza:
sudo dnf copr enable alternateved/eza
sudo dnf in eza

Enable non-free repos:

sudo dnf install dnf-plugins-core

Dropbox:
sudo dnf in dropbox (after enabling copr repos?)

sudo dnf copr enable @neurofedora/neurofedora-extra

App indicator needed for Dropbox (and nice to have for Insync):

sudo dnf install gnome-shell-extension-appindicator

sudo dnf install libappindicator-gtk3

sudo gnome-extensions enable appindicatorsupport@rgcjonas.gmail.com

go to Gnome extensions web page and turn on appindicator

Zed:

curl -f https://zed.dev/install.sh | ZED_CHANNEL=preview sh

install ruff extension and modify settings file per: https://docs.astral.sh/ruff/editors/setup/#zed

Warp Terminal:

https://app.warp.dev/get_warp?package=rpm

Insync:

download rpm from https://www.insynchq.com/downloads/linux.... then

sudo dnf install xxxxxxDOWNLOADED.rpm

Kmymoney:
sudo dnf in kmymoney

Pycharm:
sudo dnf copr enable phracek/PyCharm
sudo dnf install pycharm-community

need to install chess and svglib using pip3 install chess and then same for svglib

fisher for fish terminal:
curl -sL https://raw.githubusercontent.com/jorgebucaran/fisher/main/functions/fisher.fish | source && fisher install jorgebucaran/fisher

Whatsapp
sudo dnf copr enable nunodias/whatsapp-for-linux

multimedia codecs (free):

sudo dnf -y groupinstall multimedia

Set up Windows on KVM/QEMU: (https://medium.com/@nkav2447/run-virtual-machines-on-fedora-40-kvm-qemu-setup-aaaa20a50460)
sudo dnf group install --with-optional virtualization

Then follow https://archsetup.blogspot.com/2023/11/install-windows-11-on-virt-manager.html

Disable a repo (dnf5):
sudo dnf config-manager setopt insync.enabled=false 

Also can delete from yum.d directory.

Format to add a repo(dnf5):
sudo dnf config-manager addrepo --set=baseurl=https://packages.microsoft.com/yumrepos/edge

Always have grub menu show

sudo grub2-editenv - unset menu_auto_hide

Nvidia drivers problematic on Rawhide:

https://itsfoss.com/install-nvidia-drivers-fedora/

https://linuxcapable.com/how-to-install-nvidia-drivers-on-fedora-linux/

Reinstall kernels:
sudo dnf reinstall kernel kernel-core kernel-modules kernel-modules-core kernel-modules-extra

Map mouse button to SUPER_L:

sudo dnf install input-remapper
sudo systemctl enable --now input-remapper

"KEY_LEFTMETA" is the super key you need

Specify specific kernel (if latest Rawhide kernel not supporting your hardware)

sudo sh -c 'grep title /boot/loader/entries/* | cut -d " " -f2-' 

sudo micro /etc/default/grub    set GRUB_DEFAULT to your preferred kernel in quotes (full name from previous command)

Probably also want to sudo micro /etc/dnf/dnf.conf  and write installonly_limit=6 under 

"[main]" to increase the number of kernels kept so your working kernel doesn't disappear during an update

Downgrade from Rawhide to 42 (need to disable RPM fusion repos first):

sudo dnf distro-sync --releasever=42 --refresh --disablerepo rawhide \ --enablerepo fedora --allowerasing --best

Will probably need to reinstall kernels (see above) and get rid of old kernels: sudo dnf remove kernel\*-6.*

 followed by sudo grub2-mkconfig -o /boot/grub2/grub.cfg

Final Tweaks

•  In System Settings app:
• Uncheck Suspend Session in Power Management, Energy Savings (I've had back luck with corrupted suspends that cause boot failure)
  
•  Turn on numlock in Input Devices, Keyboard
•  Turn on night color in Display and Monitor, Night Color

• In right-click Display Settings, set up random slide show with preferred wallpapers

• sudo su and then EDITOR=micro visudo  to get rid of update password timeout
  

  Defaults passwd_timeout=0 

• sudo micro  /boot/loader/loader.conf  to set longer time for boot menu
• Set up Printer.  HP is easy using HPlip.  

Set up Printer:

• For Brother Laser printer: download linux deb package from Brother
• yay -S dpkg
sudo dpkg -i --force-architecture hll2480dwpdrv-4.1.0-1.i386.deb
Then set up in KDE add printer; manually point to ppd file at /usr/share/ppd/brother/XXXXX.ppd

socket://192.168.4.174
• and https://support.cc.gatech.edu/support-tools/howto/direct-ip-printing-unix 
• yay -S brother-hll2370dw
• Set up in KDE System Settings, Printer
• Select AppSocket/HP JetDirect, input ip address of printer, and manually add ppd file from /opt/brother/Printers/HLL2370DW/cupswrapper/brother-HLL2370DW-cups-en.ppd
  

crontab:

yay -S cronie

sudo systemctl enable cronie.service && sudo systemctl start cronie.service

paccache cleaner:

yay -S pacman-contrib

sudo systemctl enable paccache.timer && sudo systemctl start paccache.timer

In cachyos-hello:  check Ananicy Cpp enabled, Bpftune enabled and Sysemd-oomd enabled

# For zen kernel 

sudo pacman -S linux-zen linux-zen-headers

copy linux.conf entry in /boot/loader/entries to linux-zen.conf and edit accordingly

sudo mkinitcpio -P

# For firewall (laptop)

yay -S firewalld ipset ebtables
sudo systemctl enable --now firewalld

sudo firewall-cmd --add-service libvirt --zone=libvirt --permanent

for config: firewall-config

Install Windows 11 on Virt-Manager

 Virt-Manager will have been installed in base install.  But to enable it (make sure SVM, or whatever virtualization is called in your BIOS is enabled).

From https://computingforgeeks.com/install-kvm-qemu-virt-manager-arch-manjar/

sudo pacman -S qemu-full virt-manager virt-viewer dnsmasq vde2 bridge-utils openbsd-netcat dmidecode iptables libguestfs edk2-ovmf swtpm

Then enable and start libritd.service

sudo systemctl enable libvirtd.service
sudo systemctl start libvirtd.service

sudo micro /etc/libvirt/libvirtd.conf

Set the UNIX domain socket group ownership to libvirt, (around line 85)

unix_sock_group = "libvirt"

Set the UNIX socket permissions for the R/W socket (around line 102)

unix_sock_rw_perms = "0770"

Add your user account to libvirt group. 

sudo usermod -a -G libvirt $(whoami)

newgrp libvirt

Restart libvirt daemon.

sudo systemctl restart libvirtd.service

Section below is quoted directly from https://linustechtips.com/topic/1379063-windows-11-in-virt-manager/

Prerequisites:

Before starting, you need the following:

• Windows 11 .iso from Microsoft [link]
• OVMF - you need this for UEFI/secureboot. I used edk2-ovmf from the arch official repos.
• SWTPM - you need this for TPM emulation. Again, i used swtpm from the arch repos.
• qemu & virt-manager - if you don't already have these installed, they'll be in your distro's repo, more than likely.
• virtio - once you have your VM set up, mount the latest image from here to install virtio drivers for things like networking [link]

Getting started:

In Virtual Machine Manager, create a new VM from the top-left corner.

For step 1, choose local install media.

For step 2, pick your Windows 11 iso. if it's not in the drop-down, choose it by clicking "Browse... > Browse local". It'll auto-detect the OS as Windows 10, this is fine.

For step 3, set your memory and CPU cores. the default (4gb & 2 cores) are the minimum for W11, so I set my RAM to 8gb, but you can always change these values later.

For step 4, make a virtual disk image. The minimum drive size for Windows 11 is 64gb, so it needs to be at least that big.

For step 5, choose your VM name, and then tick off Customize configuration before install.

Final setup:

RECENTLY I HAVEN'T DONE THIS (JUST LEAVE UEFI): In the overview section, set Firmware to UEFI x86_64: /....../OVMF_CODE.secboot.fd. It has to be secure boot, otherwise Windows 11 won't install. While I was looking into this, I saw some things saying OVMF_CODE.ms.fd instead, if your list has that, that should work as well.

In boot options, tick off your virtual CD-ROM drive, and then set that as the highest boot priority:

->

 

Change video to Virtio

Finally, add a virtual TPM module. the defaults (CRB, Emulated, 2.0) should be fine. 

 

You shouldn't have to manually start the virtual network service, but if you do it's  sudo virsh net-autostart default

if no internet:

sudo systemctl start iptables.service
sudo systemctl enable iptables.service

sudo systemctl restart libvirtd.service

sudo nano /etc/libvirt/network.conf

write the following:
firewall_backend = "iptables"
