Hello!
First post in the forum. Happy to post on a forum like it's 2003 
For a little bit of context. I installed Zorin OS education on a laptop for my son a few weeks ago. The laptop is a Lenovo ThinkPad L14 Gen 1, i5 and Intel® UHD Graphics (CML GT2). The laptop is second hand and was blocked on a boot-loop with it's initial windows install. Considered good for the bin, we salvaged it and had an workshop with my kids trying to bring it back to life. A lot of trial and error, thought we couldn't do it but finally managed to boot it on the usb drive with the image and install Zorin 18!
Everything was fine for two months no trouble at all! We didn't have the original charger so we bought a 90w usb one. No problem there either. The USB port would be used with a small dock to charge and display on a second screen.
After the last update this USB port is like dead. No charging, no display on the second screen.... We have to use another usb-c port to charge but it isn't a display port.
So we tried an other charger same result. The charger is fine works with other devices. The dock works with an other device. Nothing is recognized on this port. Like it's dead.
So I turned to Mistral AI (sorry) to see if a quick fix was possible. it made me do some command lines to find the problem like:
lsmod | grep -i thunderbolt
lsmod | grep -i usb
sudo systemctl restart bolt
but nothing worked...
So here I am hoping someone had similar issues and knows what to do!
Thank you if you read my message (think it's maybe to long)
Oh and important note I'm a total Linux newbie if you couldn't tell
And also today i did an other update hopping it would solve the issue... but it didn't
Are you on Zorin 18? Recently there was a kernel update to kernel 6.17 which makes many problems on some computers. You could test to boot into the older 6.14 kernel.
During boot press esc key (or left shift key if you have a legacy BIOS) permanently to show grub menu.
In grub menu select "advanced options for Zorin" and choose an older kernel to boot from.
Okay @Forpli thanks for the response. I am on zorin OS education 18. I didn't have access to the grub menu. So went to a page of the forum GRUB menu were I learned how to change the timeout.
Then could access the GRUB menu and advanced settings. There were 4 choices; 2 for the 6.17 and 2 for the 6.14. I chose de 6.14 normal not the recovery. But it didn't change the status of the display port.
Okay tried again with the 6.14 recovery mode but same result.
If you run:
dmesg -w
In terminal, then plug into the USB, does the terminal relay any messages?
Hi @Aravisian it says the operation is not allowed
dmesg: Kernel Buffer Failed to Read: Operation Not Allowed
my system is in french by the way so the line up is translated
(fun fact buffer in french is not allowed on the forum)
Sorry...
sudo dmesg -w
Note: You will see a lot of output listed - your interest is in New Output after plugging int he USB.
Okay a lot of lines
one keeps comming up
[ 1151.855989] audit: type=1400 audit(1771577879.187:343): apparmor="DENIED" operation="open" class="file" profile="snap.firefox.firefox" name="/proc/pressure/memory" pid=3788 comm="MemoryPoller" requested_mask="r" denied_mask="r" fsuid=1001 ouid=0
but i don't know how to search "new" ctrl + f doesn't work
Don't think it's relevant in fact
That line is unrelated to USB
If you want to narrow it:
sudo dmesg | grep -iE 'typec|thunderbolt|usb|pd|altmode'
If you are not seeing any output, that means a firmware fault is likely.
It could also be hardware - I am not sure if you tried testing that functionality.
It is very late here, so I am going into a coma.
Maybe this is more relevant:
[ 1113.660806] workqueue: acpi_ec_event_processor hogged CPU for >10000us 5 times, consider switching to WQ_UNBOUND
notice i'm still on the 6.14 recovery boot
no problem! Have a nice coma! wil try what you suggested
Ok, this is a PCI event.
You might try fully powering off the computer, removing the battery and holding down the power button to fully reset the EC
Then power up and test.
If that does not work, can try kernel parameter
usbcore.autosuspend=-1
Remember, you are using usbcore.autosuspend=-1 and not nomodeset
and run
sudo update-grub
after saving the file with changes.
Thanks a lot @Aravisian I'll try this.
Just in case this is what I get with the previous comandline
