i had dual boot till this morning due to some files which were in windows were essential. So i backed up all those things in a CD. i have completely installed ubuntu 8.04 in my machine today (1 hour ago) by giving the option while using boot CD "Guided - SCSI (0,0,0) 80GB SATA" and i got ubuntu completely installed wiping out the Windows xp which i had. now in my top panel of ubuntu i have noticed 209 updates are available. the problem is some days before when i had dual boot (windows & ubuntu) i got kernel update to 19 and after updates i got only blank screen. Regarding that i posted threads here and some what satisfying reply i got. i was using kernel 18 then using grub loader.
My questions is as follows:
Presently i got (after completely installing after wiping windows) the kernel version 16 generic, and in my update list i found kernel update to 19. Please tell me if i got kernel update to 19 will i get the blank screen again. What i can do now, shall i go for kernel update to 19 or not? Please suggest me regarding this. Also tell me what is the command to get details on xorg which is presently in my PC. i can post the results of that command (if u guys gimme) so that u can suggest me probably to get kernel update or not. Also tell me is it a bug in ubuntu that after every kernel update everyone gets blank screen. please help me, am confused and of course i dint installed any updates yet after installing Ubuntu hardy heron.
NOTE: i haven't installed restricted drivers (ATI graphics driver Radeon xpress 200) yet.

-->a) I want to limit the core file size but linux is not limiting the core file size to specified size...
if i limit core file size using(ulimit -c) (keep ulimit -f unlimited)
ulimit -c 10, then core file generated is of 12288 bytes
ulimit -c 20, then core file generated is of 20480 bytes
ulimit -c 30, then core file genearted is 0f 32768 bytes
i dont know what is the funda or on what fators does ulimit limits core file size
if it limits , for ulimit -c 10 , it should limit to 10*1024 bytes i.e 10240 bytes
but core file size is crossing 10240 bytes, and the core size generated is of 12288 bytes.
for ulimit -c 20 , core file size is 20480 , which is again 1024*20
again for ulimit -c 30 , core file size is 32768
[root@localhost three]# ls -la /tmp/corefiles/

-->b) If we go for ulimit -f option(which limits core file size)
(keeping ulimit -c unlimited)
ulimit -f 1 then core file generated is 1024 bytes
ulimit -f 2 then core file generated is 1260 bytes
ulimit -f 3 then core file generated is 1260 bytes
ulimit -f 5 then core file generated is 5120 bytes
ulimit -f 10 then core file generated is 10240 bytes
now for ulimit -f 1, core file size is limiting to 1024 bytes,
for ulimit -f 2, core file size is limiting to 1260 bytes,but it should actually limit to 2048 bytes?
i am not able to come to a solution please help me
thanks in advance,
