Ive run ubuntu hoary (2.6.10) and suse 9.3 (dunno, below 2.6.12 anyway) and they both work with SMP/HT fine. After trying ubuntu breezy and Suse 10 (i want to switch to suse 10 fulltime btw) i notice a lot of lag and slow boots which seems to be down to HT/ACPI. These use kernel 2.6.12 and above.
If i dont use the smp kernel in both it is fine. However its not HT as i found when i tried suse with ACPI=HT boot command. This disables all parts of acpi except those needed to enable HT from what i read. It works regardless of the error messages i get during boot about some irq`s and pnp bios disabled, but i have no power management features for the laptop.
If i override suse`s choice to use smp kernel and choose default kernel its fine, and sees 1 cpu as expected, but i dont know how much of hit id be takin in performance with it. "default" is what? 386, 586, 686?
Anyone got any thoughts?
Also one other question about DPI in kde. 1680x1050 wsxga LCD is at 129x126 dpi. Ive added -dpi 75 to the /etc/opt/kde3/whatever/whatever/Xservers file which is supposed to fix it, but does nothing. any clue?
Update: the file kdmrc is the one to fix it. Serverargslocal line... nice now i can have 96dpi with MS fonts (call me gay if u wish)
thanx
