I was wondering why this beast was slower in starting X than my (with
display mechanically broken Toshiba Portege 3110CT) Subnotebook with
PentiumII 300Mhz, 192 MByte and a 7 GB HDD. from the last millenium.
(I use it as xterminal right now!)
sw: a system mixed from unstable and the grml distro
kernel 2.6.17-grml
I did init 5 (for Xserver )
ps ax and checked PID for the gdm processes
strace -f ... PID (2*)
ALT F7
login in with my $USER $PASSWORD
CTRL ALT F1
init 2
I found that 427 accesses for /etc/ld.so.nohwcap were happening,
and no file there.
touch /etc/ld.so.nohwcap and it maked 822 accesses, but slightly
faster.
I think this is a performance killer.
Mailingliste grml recommended to report it to debian-x, so here we go.
Please feel free to ask more, also that I did deinstall this Xorg server
now.
regards
