TLXOS 4.8.1


TLXOS 4.8.1

Bug fixes:

  • all bug fixes from TLXOS 4.9.1, 4.9.2 and 4.9.3 that are relevant to the software versions present in TLXOS LTS
  • Jessie version of Cloudprint uses obsolete Google API and therefore cannot work

New features:

  • add support for Pi 400 (RPi only), except for keyboard shutdown sequence, which Jessie's old systemd version doesn't support
  • add Video Conference mode using Teams-for-Linux (, except on RPi IoT
  • Maintenance mode now sets the root filesystem size to 1.125 gigabytes and activates swap on partitions detected as swap space, permitting RePC and SFF upgrades on devices with only 1 GiB of RAM with the aid of a swap device

Special customer requests

  • added out-of-tree rtw88 driver on RePC
  • added out-of-tree rtl8822bu driver on RPi
