I did yet another clean install of openSUSE 11.2 64 on my desktop computer, did updates, added Nvidia and Packman repos (it's not a repo problem as I tried it several times on a totally clean install), added codecs and stuff as advised by caf.
I updated the DVD drive firmware earlier today.
My user is a member of ALL groups.
Drive is an LG GH22NSS50 (sata)
It all works (with the same DVD-RW) under winxp on the same machine.
Is it HAL or something else that blocks permission to devices?
I'm really getting sick to death of this problem, and would be happy just to get rid of anything blocking permissions to the DVD drive.

I installed Ubuntu 9.10 a few days ago, did the updates, surfed on the net, mounted a slave drive and read everything on it, shut down, pulled the slave out and now I can't boot.
After the post screens I get: Verifying DMI pool data

I think way back I had to reinstall grub or something on another machine I had but I don't remember anything about it. Is that what I have to do and how? Is it because I pulled that slave drive out that this happened? I want to get some more files off the slave as I wasn't finished.
I'm trying for the first time to work with sounds and edit them. I'm trying to use Gnome Wave Cleaner and don't know what to do about the error.

I am new to k3b and trying to burn an iso and get the following message during the burn process .
"CDrecord has no permission to open the device".
I JUST registered here as I have not used Linux in several months. Linux and I have been and off and on relationship, but after I realized Ubuntus limitations Ive pretty much only dealt only with Debian (on PPC as well as x86, and also some Suse on x86).
Anyway, so I just picked up a couple Sun Ultra 5s for free. One had 256MB RAM (4 x 64MB), a 4.3GB IDE HD (no SCSI in the Ultra 5), and booted fine in Solaris up to the login screen at which point it wasnt really any use to me since I dont know the login name or password, and really want to run Linux anyway. The other I am told needed a firmware (chip?) and basically didnt do much more than power on. However, it had a 40GB HD and 2 x 128MB RAM modules. So, I replaced the 4.3GB drive with the 40GB, and replaced 2 of the 64MB RAM modules with 2 128MB modules, for a total of 384MB RAM.
BTW, both machines have the 270MHz Ultra1 CPU. Anyway, I used my main Windows x86 machine (which Im on now), downloaded the Debian SPARC net install, and burned it to a CD. Put the CD in the Ultra 5, installation proceeded nicely, though with one disconcerting message stating the urgency of which a reboot was required (though still telling me to wait for installation to finish). I mean, the whole installation process basically went perfectly except that one odd message.
So, when install is complete, I choose finish installation, the machine reboots, ejects the CD, and then ultimately get a message saying "cant open boot device". I am very new to Sun hardware, and am by no means an expert to Linux. The only thing Ive really tried so far is to type "boot hda" which only causes the same message to appear.
From previous experience, I have written on paper the info for all of my partitions. So I think my Debian install is sitting there waiting to be utilized, but the Sun hardware is oblivious to the fact that theres a perfectly good OS on the machine yearning to be booted.
I have been trialling Slack 13.1 on a spare 32b system for a couple of weeks, and today I took the plunge and put it on my main machine. I completely re-partitioned the drive (using the Slack disk) and installed Windows7 on one partition and Slack 13.1 on another. The install worked fine and I tested that it boots from LILO into both Windows and Slack perfectly. I then ran:
slackpkg update
slackpkg install-new
slackpkg upgrade-all
And since then it fails to boot with the following:
Code:
VFS: Cannot open root device "802" or unknown block(8,2)
Please append a correct "root=" boot option; here are the available partitions:
0840 488386584 sde driver: sd

I have seen many, many similar problems when searching Google but they all seem to be caused by different things.
I am using a kernel with no initrd. I have had this kind of panic before. Usually it means that the kernel can access the hard drive because the driver for the controller or filesystem isn't built into the kernel.
The kernel is 2.6.34 vanilla.
My IDE controller is a Silicon Integrated Systems SiS 5513, and I built the driver for it into the kernel BLK_DEV_SIS5513=y
My /boot (hda1) is ext2, and everything else is ext3
EXT2_FS=y
EXT3_FS=y
My grub entry (hda2 is my root partition) kernel (hd0,0)/vmlinuz root=/dev/hda2
I have installed it (11.3) with KDE desktop.I have a problem with openening a device (harddisc) directly from sysinfo:/It is a ext4 partition, but also with my others (ntfs), this error occurs...

I was trying to burn an .iso with K3b a little while ago, and had some problems. First of all, even though I chose 8x to burn my (16x) DVD, it switched to 11x or 12x around halfway through the burning process. There were also some ticking noises that I'm pretty sure were coming from the DVD writer, not terribly loud, but noticeable. This had never happened before. Finally, it got stuck at about 98% (but not frozen, as the time elapsed kept going), and did not finish burning--got an error message (and a bad disc): "cdrecord has no permission to open the device"
I inspected the disc and there was one dark spot (on the dye) about halfway through the disc, very thin and couple of millimeters long. (This was present only after burning). I'm using Ubuntu 10.04, K3b version 1.91.0, Lite-On DVDRW SHW-160P6S

I've made a lot of progress getting my easycap 2.0 usb capture device to work with ubuntu 10.10. I've got the picture up any everything works great. But about a minute into the stream it just freezes, I need to go into "playback" and either pause then play, or click "next", it then refreshes and works again for another minute or so. I'd believe it if someone says faulty hardware because the easycap is cheap, but I don't think that's the case. Additionally, is there any way to set VLC so that when I open it, it automatically opens with my video capture device (/dev/video0) so that I don't have to go into the options and change it every time?
View 1 Replies View RelatedI have sendmail running on my centOS 4.6. My lamp server also runs on it. I want to send mail through php mail function. when i execute php page, which fires the mail function, it takes so much long tim1 say even 1 minute, and at last displays that message sent successfully. Suppose, destination address is [URL].... I did not get any mail there. My server is running in LAN. I checked the status of sendmail, it shows me that it ios running. when i issue "nmap localhost" it shows me that SMTP port 25 is open, but when i issue "nmap myserver" (192.168.1.20 myserver ( written in hostfile)), it does not show that SMTP port is open.
I checked the /var/log/maillog, one person in my previous post advice me to see that. There it shows that message is accepted for delivery...but i do not get any mail in my destination, even not in spam folder. One more confusion is that, in my case my server is in LAN and if I am at all enable to open the SMTP port on it, does i need to open SMTP port on my router (which connects my LAN to internet) also needs to open? I think no, because SMTP is application layer protocol, it will wrap my mail in IP packet, which router just need to forward. am i right?
