XF4, speed and keyboard problems

XF4, speed and keyboard problems

[Giuliano Pochini]

Hi! I finally installed XF4. It seems faster for most of operations (windows
movement is smothes, xscreensever runs fater, etc), but all visualization
plugins for Alsaplayer and xmms are 30% slower according to CPU usage
(print_a_bitmap_on_the_screen() is slower ??).

Anyway... the real problem in another one: I can't get different codes for
left/right shift control and alt keys :(((
I tried to patch mac_keyb.c to never translate R to L codes (it worked for
XF3) without success. Also, I can't anymore
emulate central mouse button with L_alt+L_button :-(((

I have a Microsoft (bleah) USB keyboard (which do send separate L/R codes in
console) and kernel 2.2.16p)

Help !!

Bye.

CPU usage of the plugins or the server? You have to sum up both to get the
actual CPU usage with both versions of X.

Can you please provide numbers?

  Oops, this one works, sorry.

Overall performance.

I have to reinstall the old version. I have no time now, sorry. Perhaps next
week end...

I made these test with x11perf:


test             4.0       3.3.6-XPmac_aty128
---------------------------------------------
putimage100      669           788
putimagexy100    224            83
shmput100       1075          1300
shmputxy100        6             6   (bleah)
putimage500       23.9          28.1
shmput500         43            51.6


I don't know how much this test is valid, since I run the old
XPMac server over a 4.0 environment (libs, fonts, tools, etc.),
anyway the speed loss in put-image calls is around 20%.

Bye.
