My Kubuntu 20.10 won't let me log in. It says:
xsession: warning: unable to write to /tmp; x session may exit with an error
I think the system updated it's kernel before it happened.
What can i do to fix it?
I'm trying to scan a document with a Epson ET-2750-Scanner using xsane. I always get the errorcode: "Invalid argument".
Printing with the ET-2750 works fine, just scanning doesn't. I've tried connecting it over USB or Wifi, it doesn't make a difference.
xsane finds the printer:
But it can't scan:
What do I do?
I've got Ubuntu 18.04 LTS on a Dell E7250. The o2-micro-SD-card-reader doesn't work after installation so I have to do
sudo rmmod sdhci_pci
sudo rmmod sdhci
sudo modprobe sdhci debug_quirks2="0x80000000"
sudo modprobe sdhci_pci
at startup.
The blog post Workaround for broken O2 Micro SD card reader support since Linux kernel version 4.1.8 says that I have to edit a *.conf file to have it happen automatically at startup, but it doesn't say which file and how exactly I have to edit it.
What file do I have to edit?
