Regarding #1, look at TLP, from the
$ pamac search tlp
tlpui [Installed] 18.104.22.168-1 community
A GTK user interface for TLP written in Python
tlp [Installed] 1.5.0-6 community
Linux Advanced Power Management
…and it also has a GUI, which obviously needs the usual one, so install it with:
pamac install tlpui tlp
Might be a missing driver. Please provide the output of:
inxi --admin --verbosity=7 --filter --no-host --width
When posting terminal output, copy the output and paste it here, wrapped in three (3) backticks, before AND after the pasted text. Like this:
Or three (3) tilde signs, like this:
This will just cause it to be rendered like this:
eget nisl elit id
arcu erat varius
cursus sem quis eros.
Instead of like this:
Sed sollicitudin dolor eget nisl elit id condimentum arcu erat varius cursus sem quis eros.
Alternatively, paste the text you wish to format as terminal output, select all pasted text, and click the </> button on the taskbar. This will indent the whole pasted section with one TAB, causing it to render the same way as described above.
Thereby increasing legibility thus making it easier for those trying to provide assistance.
For more information, please see:
If your language isn’t English, please prepend any and all terminal commands with
LC_ALL=C. For example:
This will just cause the terminal output to be in English, making it easier to understand and debug.
