I moved from Ubuntu to OpenSUSE tumbleweed recently and I must say it is lovely. The OS is still the Linux I learned when running slackware (with some modern extras that I have learned to live with) while still giving me most of the polish of Ubuntu. Some things were of course strange. Having to type the disk encryption password twice being standard behaviour is pretty strange, and not getting to set the keyboard lay…
After reinstallation with the correct configuration though, it was smooth sailing. The only other change I had to make was disabling KWallet so that it connects to WiFi without prompting me for a decryption key.
