X230 and El Capitan - small issues

Finally managed to get an older dream of mine come true: triple booting a laptop.

 

For those wondering how I did it:

 

 

  • I kept the original win7 partitions, upgraded to win10, did a refresh to clean up the installation
  • Booted into Hiren's boot CD to mess with partitions. Resized the EFI partition to 250MB (by moving stuff around), shrinked the main Windows partition make space at the end, created a 50GB HFS partition, the rest of the space was kept unallocated after that partition
  • booted into the MacOS installer, deleted the HFS partition, created a new one in its place (seems the installer cannot see unallocated space, so you have to use a dummy partition), followed normal procedures
  • installed Ubuntu
  • adjusted Clover boot entries to be able to boot into all systems

 

 

Clover is used as a boot manager

 

Anyway, for OSX I've used mostly the repository from Bizzaro, with a DSDT file for my CPU (i5-3320).

Everything is running fine, including sound.

The issues I have:

  • the trackpoint ('nipple') is jumpy (no acceleration) and to get it to a decent speed I have to reduce the trackpad speed to minimum. Is there any way to control the speeds of those independently? Perhaps with the Elan touch kexts?
  • the CPU seems throttled, would make sense as the fan only spins up to <50% of its maximum speed. BIOS setting is 'max performance'.
  • I've had random issues with win/alt switching places during heavy typing sessions. Just saying this in case someone else encountered this
  • haven't found a way to boot OSX from Linux Grub, for backup reasons

I ran geekbench and the score was about half of what I should've gotten, 984 for single-core and 1800 for multi-core. I guess I need to revisit the DSDT.

 

EDIT: ran ssdtPRGen.sh without any parameters, copied the files into EFI/Clover/... and now I'm getting 3277/6216 in Geekbench. I'm happy with that, but seems a bit high for an i5-3320M.
