I recently installed Kubuntu on my Lenovo X280 with an i5-8250U processor, and I've noticed it has become noticeably slower. My boot time increased from 14 seconds to 35 seconds, and the overall performance feels sluggish. I'm new to Linux, so I'm not sure what might be causing this delay. Is there something I might be missing or need to adjust?

It's actually pretty common for Windows to boot faster than Linux on desktops, even with better hardware. So don't feel bad about that! Just focus on finding a setup that works best for you.
To diagnose your boot time issues, you can use the command `systemd-analyze time` to see where it's spending most of its time. If it’s taking a lot of time on the firmware, check your motherboard settings. Additionally, ensure you're using Wayland instead of X11, as Wayland generally provides better performance with Kubuntu 25.10.
When you switch to a new Linux distro, the choice of desktop environment can greatly impact performance. Try out lighter DEs like Xfce or Cinnamon. I've had great experiences with Linux Mint Xfce and Xubuntu—they’re both user-friendly and run smoothly on similar hardware.
Keep in mind that comparing boot times between Windows and Linux can be tricky. Windows often uses hibernation, which makes it boot faster than a complete shutdown. If you're still experiencing slow boot times, consider trying out a different desktop environment as suggested above.
Exactly! Plus, performance can vary widely based on the DE you choose. It's worth exploring lighter options.
KDE Plasma is known to be resource-heavy, which might be why you're experiencing slowness. You could try a lighter desktop environment (DE) like LXQt, which is used in Lubuntu. This could significantly improve your performance.
Thanks for the tip on using Wayland! I’ll definitely check that setting to see if it helps.
