Hi! I switched to CachyOS about a month ago on my Lenovo Legion 5 and the process was smooth with no major issues. My usual setup is the laptop connected to a TV via HDMI, using it as my only display. When I first installed Linux I was away from home and used an older generic TV, with no problems at all. But back at my usual place, connected to my personal Samsung Smart TV (2015 model), I ran into a weird issue: After booting and logging in, the desktop appears normally for about 10 seconds, then the TV shuts off. Sometimes it powers off completely and needs to be turned on manually, sometimes it reboots on its own, and occasionally nothing happens, but when it does shut off, the standby light blinks rapidly until I turn it back on. After that, everything works fine for the rest of the session. This behavior doesn’t happen on the live USB, nor on Windows (I set up a dual boot to check). One thing I haven’t confirmed (might be nothing) is that the display refresh rate seems to drop after this happens: mouse movement feels slightly laggier, though it’s barely noticeable. I’ve tried: - Disabling Anynet+ (CEC) on the TV, no change. - The TV is not connected to the internet. Not a critical issue, just an annoying one, and I haven’t found anything online addressing this specifically. Any ideas? Specs: Intel i5-10300H, NVIDIA RTX 2060, both / and /home are formatted as ext4, GRUB as bootloader, Wayland, KDE Plasma, all up to date, weekly updates + Timeshift backups.
