I upgraded my notebook from Kubuntu 10.10, which worked well with only few (but annoying) issues. One was that once in a while the internal NIC will behave funny: either it won’t connect at all, or only 100 or 10 MBit/s instead of GBit/s. The fix is to power the notebook off, remove the battery, wait few seconds, then put back battery and power.
The other problem is that if you tax the CPU too much (think: compiling Linux kernel using “make -j” to keep all CPUs busy), it’ll actually shut down as the CPU gets too hot. The price you pay for having a too powerful CPU in a notebook.
So I thought, since 11.04 is out, let me try that.
Well…the good news is that nothing important broke.
The bad news news is that small things broke:
- Firefox (now 4 instead of 3) knows no Adobe Flash anymore. However Google Chrome does. Odd, but works for me.
- The CPU fan started and kept on running at full speed. See bug report here. The highly in-elegant fix is to limit the CPU speed severely.
- /proc/acpi/thermal_zone no longer exists. That is now using the /sys interface and it’s in /sys/class/thermal/thermal_zone*/. Some tools still use /proc only, which makes them display no temperature anymore, although the kernel knows the temperature.
