Upgrading Kubuntu 22.10 to 23.04

My job? Computer Sisyphus. I work on cryptography. I like videogames and books.

Did an in-place upgrade this morning from Kubuntu 22.10 to 23.04. I was a little worried about this as the last desktop Linux I used (Mint) suggested doing a full install from scratch, rather than in-place upgrades. Hopefully they’ve fixed that problem, because it’s really the opposite of being a noobie-friendly distro. Also, in the distant past, Mandriva (IIRC) used to pooch its kernel and grub upgrades for me every time.

The update appears to have worked perfectly, with the exception of Telegram vanishing. That was easy enough to re-install via Flatpak.

With any luck this will fix the “wifi goes into low-power mode randomly” bug I’ve been annoyed by since installing 12.10. Luckily(?) the work-around for that is just to cycle the wifi connection, but it’s definitely irritating.

The award-winning MMORPG Final Fantasy XIV works, and I haven’t noticed anything else missing or broken.

So far, so good!

It’s possible the wifi issue has been fixed, but I won’t know for sure for a few days. I was online all of yesterday afternoon without any slowdown.

I did have to re-run the installation script for System Tray Extensions so it could rebuild its Python environment. I need this to turn on my keyboard’s backlight (why the default boot state isn’t “on, white” is baffling… good thing I know how to touch-type).

I also took this opportunity to clean up the last old-style apt PPA key I had (for Remember The Milk). The instructions for doing this can be found on askubuntu.com.

Literally a minute after I posted the update my wifi speed dropped down to about 50kbps, soooooo… time to find the instructions for disabling low-power modes for the Intel Wi-Fi 6 AX200NGW.

Resetting the wifi connection only brings me back up to 130Mbps; normally I get 500-600Mbps. And it’s gone back down again while I was typing this.

sudo modinfo iwlwifi | grep 'parm:' will show you the current settings. The suspicious ones (IMHO) are power_save and power_level:

parm:           power_save:enable WiFi power management (default: disable) (bool)
parm:           power_level:default power save level (range from 1 - 5, default: 1) (int)

Using ip link, I see that my wifi is wlp62s0. Turning off power saving on this interface (via sudo iw dev wlp62s0 set power_save off; use get power_save to check the value before/after) does nothing to improve my speed. Bouncing the connection turns it back on, too. I’ve added options iwlwifi power=off to /etc/modprobe.d/iwlwifi.conf, hopefully that’ll help after a reboot.

Well, that didn’t help; iw dev wlp62s0 get power_save shows that power saving is still on.

Angry cat flips table!

Maybe iw wasn’t the right command? sudo iwconfig wlp62s0 power off seems to have gotten me back up to normal wifi speeds at least for now… I still don’t seem to have a way to disable this on boot, and I’m expecting it to reset when I put the system to sleep.

This is totally riveting isn’t it? Hopefully these instructions will help someone in the future, I dunno.

This post on askubuntu.com suggests editing /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf (change wifi.powersave from 3 to 2; magic values!). Guess I’ll see…
