After-installation remarks that won't fit in installation report
Hi,
I have already described my experiences of installing Sarge in #274994.
(And btw. on my sparc machines, U10 and Blade150 I was beaten by #275761
and "dead keyboard after d-i boot" respectively)
Now that I have used my i386 machine for some time, some notes.
1. The system has very noticably worse responsiveness when copying big
files from one disk to another. Actually the machine was so busy
copying that only thing I was able to do was ps and renice the copying
to process to +20 to make the machine usable again.
Maybe my machine is not speed daemon (AMD k2-6 500MHz) but this was NOT
the case before I reinstalled the system. After I confirmed this effect
is repeatable I started to think it could have been because I had kernel
configured to make use of "Preemtive" feature. I had no other patches,
and until now I had NO idea it could have made so big difference!
(I used to use something like self-compiled, but otherwise stock 2.6.5)
I plan to recompile the same kernel from debian's source, changing only
this one option to check whether this actually is the issue. But I
guess I might not be the only one experiencing that kind of problems.
Couldn't we have at least one "desktop kernel" in Sarge? It could be
built from the same source as the "standard" one, just with different
options.
2. On my sparc machines (Blade 150) I am forced to use on-board graphics
card, because Linux does not handle the additional PCI card at all (Sun
said they will never release any docs on that one). While doing some
experiments (tunning modelines to maximize monitor's resolution to some
nonstandard 1504x1128) I turned off XFree86's "dbe" module (double
buffering).
Not exagerating, the graphics got like 4 times faster! I did the same
trick on my home machine and I am (again) able to play movies. The big
question is why do we want this module to be turned on by default?
The debconf presents list of modules with this module turned ON by
default, and suggesting (IIRC) one should leave them all turned on.
(my home machine has NVidia TNT2 AGP card used with free "nv" driver)
I already explained difficulties I had with installing Sarge via
SDL link in #274994, so I guess that'd be it.
I am not on the list, so please Cc: me on comments.
Cheers,
Grzegorz B. Prokopski
