Hi all!
T420 + Ubuntu 24.04.2 LTS - I could write to /proc/acpi/ibm/fan
for fan control.
That worked.
T420 + Ubuntu 25.04 - Now I get:
====================================
% cat fan_2.sh
echo "level 2" > /proc/acpi/ibm/fan
% sudo ./fan_2.sh
./fan_2.sh: 1: echo: echo: I/O error
====================================
Known issue (after upgrading)?
is anyone aware of a right-angle adapter for the (pre-usb) thinkpad ac
plugs? or detailed specs on what to search for?
i always need the ac/dc unit on my right side, and thus the dc cable has
to head right from the thinkpad's socket. and i lost one recently due
to cable stress. (the arc was welding bright.)
i'd like to avoid any re-occurrence of that.
(luckily i had a spare a/c supply from a previous thinkpad.)
thanks,
-JimC

I just tried my old X61t and found that the stylus didn't work under
Fedora 42 (a "live" USB stick).
It still works under Fedora 24.
Any thoughts? Could this be due to the switch to Wayland?
hi all,
any idea if it is possible to fit a touchdisplay into a t580 with a
'normal' display ?
I'm somewhat puzzled by the connectors, as there seem to be 20,30 and 40
pin connectors.....
regards

After 30 minutes the laptop does not turn off.
Try spamming ESC after hitting power off, until a wall of text appears.
When it stops or loops send a photo or video.
Or you may shut down and in a GRUB menu press E to edit the option. Remove
the words quiet and splash from it. and press CTRL+X to start. A wall of
text should appear then Ubuntu logo. Log in then shut down as usual. Then
you have the wall of text. Now it should hang or loop. Show photo or video .

> This is a new Ubuntu 22.04.5 Pro installation. Initially up until December 28, 2024 there was no issue a complete powering off. Clicked on the pop up screen to upgrade from 22.04 to 24.04 and this is when the issue began. I have upgraded the bios from 1.75 to 1.80, followed and completed a number of suggestions but the laptop will not turn off. Interesting enough I am testing a dual-boot x470 with the same linux distro plus windows 11. This issue does not happen on this laptop.
I think you should press ESC on the exit splash screen and show what
happens (a recording I think. Also, does it turn off when left in that
half powered off state for 30 minutes?

I agree with Tom - I'm an old fart and prefer simple/clean.
I transitioned out of unsupported Redhat-based distros way too
late, and wasted almost a year attempting to recreate my simple
Gnome working environments with Ubuntu - very slow, very bloated,
especially on ancient T60/T61 laptops with my preferred 4x3
format screens (but never enough RAM). I read and write
scientific papers, rarely watch videos, never play games.
After that, I tried Mint ... still too much "video game"
behavior for me, but I can understand why many like it.
I then went to straight Debian (currently Bookworm 12 on many
machines, upgraded from Bullseye 11, one test desktop running
Trixie 13). Still learning and porting and upgrading apps ...
OpenVPN to Wireguard, for example.
Debian is CLEAN and FAST with minimal memory footprint. My
T60s boot in 20 seconds, and shut down in ONE SECOND. That is
important; if the Thought Police appear, my machines can be
rebooted QUICKLY to a Windows XP partition with Solitaire on
the screen.
Regards speed; all my machines have Samsung 870 EVO solid
state drives, 1TB for the laptops, 2TB for the desktops,
and large platter drives on the backup servers. I have
not tried 4TB or larger on the Thinkpads ... but I do have
tools to rewrite the BIOS tables if necessary, and have
done that to accommodate retrofitted 2048x1536 screens.
Properly configured, I can move the Debian SSDs between
laptops and desktops, for command line upgrade or
recovery from backups. I keep bootable spares, in case
I meak two minnie mesdakes.
So, yes, Debian!
