I have an AcerView F50 Flatpanel on a Cirrus Logic GD 7555 2MB an it is
doing fine with XF86_SVGA but only in the 8bit mode. When I try out the
16bit mode, which worked well when I had windows, I still get an image
on the screen, but it is very dark and without any contrast.
I tried many different settings (including modifying the horiz. and vert
sync rate), but I can't get those 16bit work.
Has anybody a clue?
Thank you

Hello out there,
I got an XL problem with suse linux 7.0 (i686)
xfree 4.0, nvidia tnt2m64 and a LG 775ft-Monitor.
I configured everything with sax2 and so far it
works fine with the nv-driver, the nvidia doesn't
work at all. I tried to update everything from the
suse homepage, but rpm hangs when it unpacks the
*.rpms.
Now the problem:
When I want to use xmms for instance, the monitor
switches of with a warning message that the
hsync/vsync rate is too low. As I said above, I
told sax2 the hsync/vsync values from the monitors
handbook. I tried it with xf86config, no effects
at all.
When that happens, it is impossible to use the
system, I can't kill the server, but the system is
still doing the jobs.
I don't use any performance features from BIOS, as
recommanded in README.
Has anybody an idea?
-j
BTW: I NEVER buy any nvidia product again. HAs
anybody an recommandation for a high performance
grafic card without any nvidia chips?

You have to recompile your kernel. In the block devices section, disable
anything to do with your cdrom (all IDE support), enable scsi support and
then go to the scsi devices section, in there enable scsi cdrom, scsi
generic and scsi emulation. I think thats where they are anyway. Recompile
the kernel and reboot. Your cd device(s) should now be detected as scsi
devices and you will be able to use them as such.

I can't use my CD-WR, and since yesterday I can't use my CD-R player as

I thouhgt I figured it out with the help of the tutorials at mandrakes
site,but that didn't work for me.
A collegae told me to check /etc/mtab
This is what was there (at this time my CD-Rom still worked)
/mnt/cdrom /mnt/cdrom supermount rw,fs=iso9660 0 0
/mnt/cdrom2 /mnt/cdrom2 supermount rw,fs=iso9660,dev=/dev/cdrom2 0 0
I changed line 1 (without any result though) in:
/mnt/cdrom /mnt/cdrom supermount rw,fs=iso9660,dev=/dev/cdrom 0 0
Mtab at this moment contains these lines (CD-rom also doesn't work
anymore):
/mnt/cdrom /mnt/cdrom supermount rw,fs=iso9660 0 0
/mnt/cdrom2 /mnt/cdrom2 supermount rw,fs=iso9660 0 0
I searched deja and found some postings that sounded familiar, but I just
didn't understand what the answers where saying. I mean, i can do what
they tell, but I would'nt inderstand the least of it. Soooo unsatisfying.
Things like mtab, fstab en conf.modules etc, I don't understand these

some. Especially the relation between all these things. Or tell me where
to find the information needed, because I'm having trouble finding my way

Upgrading the devices' firmware from 2.20 to 2.33 did the trick. Now it
seems to be working just fine. Thanks a lot for the suggestions, James.
It is really nst1. The other device is a Conner CTT8000-S. Daily backup
on this device worked all the time. Therefore I didn't expect trouble on the
kernel or modules side.

You're sure about the drives name? Never heard about
that one. Onstreams homepage mentiones only
DI30, Internal IDE, 30GB
SC30, Internal SCSI (50-pin), 30GB
SC30e, External SCSI (50-pin), 30GB
SC50, Internal SCSI (50-pin), 50GB
DP30, External Parallel Port, 30GB
USB30, External USB, 30GB
ADR50i, Internal SCSI (68-pin), 50GB
ADR50e, External SCSI (68-pin), 50GB
Onstream support features a special linux-related site at
http://www.onstream.com/support/linux/index.html
This site states:
>> ADR50 is Certified for Linux
DI30 is Certified for Linux <<
but also:
>> Support for the OnStream SC30 and SC50 will be available soon. <<,
whatever that's suppossed to mean.
Unless you've got one of these I don't think you will get any support from
them.

I have a detailed harddisk comparison of C't (german computer magazine)
next to me.
The tests for your drive give:
sequential read transfer min/avg/max: 17.6/27.6/35.9
Doing some quick tests here with an IBM-DPTA-371360 drive
(min/avg/max: 13/19/22) shows that buffered read is always 112 MB/sec,
and unbuffered is around 21 MB/sec. However, I had to run it at least
twice without doing much else, to obtain the same results.
My hdparm settings are:
hdparm -c1 -d1 -k1 -m16 -W1 -S60 /dev/hda
The system is a P3/550 with 133MHz rams, if that counts. Stock 2.2.15
kernel without any patches.

Thanks for your response. Kudzu put that line in modules.conf. What I

Date: Wed, 04 Oct 2000 12:56:02 GMT
Most often, if its simply a permission problem, its because the
permissions change on these devices when someone logs on via the
console. You can change this by editing the file
/etc/security/console.perms
so that /dev/dsp (and others) have write access for users (or whomever).
man console.perms
has more information on this.

Has anyone tested this motherboard? (For AMD Athlon Tbird processors.)
I'm having some troubles with it. It seems to POST all right, recognizes all
IDE drives, etc. When trying to load Win2K, e.g., it blue-screens, even when
trying to boot off the installation cd.
Booting Linux Mandrake seems to work ok then, from the 7.1 installation cd
at least.

Date: Wed, 04 Oct 2000 13:20:38 GMT
Hi, I have recently been having *extremely* slow connections with my
cable modem (@HOME service through COGECO in Kingston, Ontario). Slow
as in <230 bytes/second. This all started to happen after I upgraded to
the 2.4 kernel (well to 2.2.17 to 2.4) from 2.2.14...and the modem keeps
loosing its connection. Now, before I call up the cable company and
start complaining, I just want to make sure that it cannot be a
hardware/operating system problem (everytime you mention Linux to them,
they automatically say that they cannot help). Can it be something in
the setup? Was the timing with the upgrade merely coincidence?
I get my dynamic IP at bootup with DHCP protocal, and I have in my
/etc/hosts file
127.0.0.1 localhost localhost.localdomain Mintaka
130.15.26.39 lola lola.phy.queensu.ca
130.15.28.14 fisher.phy.queensu.ca fisher
with my machine's hostname as Mintaka. Also through linuxconf I have it
so that addresses are first checked through /etc/hosts and then dns.
Any help would be greatly appreciated.

My main applications will be:

- data visualization (some 3-d visualization which may require
programming with OpenGL or Mesa)
- use of StarOffice (for word processing, etc...)

Probably best to boot to single user mode first ("linux s").
Note that rebooting may well fix the problem; Linux (and Unix)
don't remove files untill they're closed.

If anyone has any idea on this I would be eternally grateful. I am at the
point where I would exchange atrocities for a solution.
I have an Athlon 700 on an Asus K7M board with 256 MB RAM and a Maxtor 30
GB drive. I'm running Mandrake 7.1 with the 2.2.17 kernel. Frankly though
the kernel and drive seem academic as I have had problems ever since going
to the Athlon even though the motherboard I have is supposed to be one of
the good ones.
I am building KDE 2 and again this is academic... it seems that whatever I
do I just need to stress the system and it's toast. I have the latest gcc
and doing a compile gets numerous internal compiler errors. Segfaults are a
way of life and often my system, which unfortunately needs to be rebooted
several times a day, shows a partition as being busy. I get kernel paging
errors sometimes when trying to unmount my drives.
I mean running the #$%%^&ing compiler can lock it up!
I have a pentium 90 firewall running the same software that has been up for
months. My wife is running my old system, and AMD K6, and I can compile
programs on hers no problem. I maintain several K6s remotely that do not
have these problems.
So what do I do? Replace the motherboard? Get a 2.4 kernel? Does it handle
Athlons better? I am sick of having to make 10-20 times to compile a
program and having to reboot after to get my system working right!
If you have fixed this problem please email me a response.

aiee, killing interrupt handler
kernel panic: attempted to kill the idle task!
in swapper task - not syncing
1737 warnings and 5 errors issued. Results may not be reliable.
Looking at the trace, I can see the cpu wasn't actually doing
anything when it crashed. Well, an interrupt occured, and that
apparently is fatal on my machine. Now I wonder why. There is not much
to go on with, except debugging the interrupt handler, which I an NOT
qualified to do.
Out of interrest, I looked at /proc/interrupts:
CPU0
0: 200596 XT-PIC timer
1: 4217 XT-PIC keyboard
2: 0 XT-PIC cascade
5: 0 XT-PIC MPU-401 UART
8: 1 XT-PIC rtc
9: 166867 XT-PIC usb-ohci, nvidia
10: 0 XT-PIC Yamaha DS-XG
11: 11417 XT-PIC eth0
12: 18506 XT-PIC PS/2 Mouse
13: 1 XT-PIC fpu
14: 483885 XT-PIC ide0
15: 16130 XT-PIC ide1
NMI: 0
Should I be worried about the nvidia driver/hardware sharing
interrupts with the USB port? That's apparently the only problem I can
see, but I have earlier had USB be shared with eth0 and the system
still crashed (though not that often).
My guess is that any interrupt sharing on this system is fatal in some
degree. I will disable USB in bios and try again.
Any suggestions?
regards,
Bernhard Ege

Whatever comes to hand will do the job just fine.

Which ever distro you get will have gnu compilers; RHL 7
is just released in the past few days and the software included
is probably as recent as any.

if you want good graphics, Matrox. Otherwise pretty much any
of the cheapies - S3, S3V, S3 Savage, i740.
btw Consider whether you would benefit from SMP; if you can
benefit from working two CPUs, the incremental cost isn't that
great compared with the overall cost of the system.

Should work. You need USB support; I gather it's in Red Hat Linux 7.
I'm using USB (for a trackball) with a 2.4 kernel. If you choose
this route there are other packages you need to upgrade -
read the documentation accompanying it.
There are refeences in the docs to assorted USB devices including
scanners, cameras et al. There may also be some supplementory
software you will want; again, read the kernsl docs.
I think you will also want sane;-). Whether you need an especially
recent version, I don't know, but it probably won't hurt.
