[ltp] X11 is slugish

[Stein Vrale]

I had this problem a couple of days ago, I felt the desktop had been
very slow lately, blamed E/Gnome as usual but then I checked
/proc/cpuinfo and saw it was in low speed. I'm mostly on AC so I don't
know how it happened, but I used the DOS PS2 SPEED option to set it to
FIXED MAX. After this my TP380 is like new again :-)

Here's the options from ps2 if anyone find it useful to try:


C:\DOS\UTILITY>ps2 ? speed

Command Syntax : PS2  SPeed   Fixed  MAX|Medium|Slow  [AC|DC]
                              Auto       Medium|Slow  [AC|DC]
Current State  :
        High       power mode : Fixed MAX
        Auto       power mode : Auto Slow
        Customized power mode : Fixed MAX
Description    : Select one of the processor speeds from the list:

                        1. Fixed MAX     (Highest Performance)
                        2. Auto  Medium
                        3. Auto  Slow
                        4. Fixed Medium
                        5. Fixed Slow


                 Specify AC when you change the processor speed for an
AC
                 operation.
                 Specify DC when you change the processor speed for a
battery
                 operation.
                 When you do not specify [AC|DC] option, the current
power
                 source(AC or Battery) is selected.

C:\DOS\UTILITY>
