I would like to remotely reboot a computer (via ssh) to a non default kernel. If I just type reboot, it reboots to the default kernel. Man reboot(8) does not give any hint so I am not sure that is possible at all. I have found nothing googling around either.
View 6 RepliesAfter reading this article openSUSE News - Forum Users Benefit from openSUSE KDE Repository I added that KDE repo to yast and switched all packages.
After rebooting it says (failsafe kernel configuration says the same):
Kernel panic - not syncing: VFS:
Unable to mount root fs on unknown block (0,0)
And stops at this string: "[<c0203826>] kernel_thread_helper+0x6/0x10" and capslock light is blinking.
Here's what to do right after applying the latest kernel security patch (2.6.34.7-0.4) to get the ATI driver back to work. Do not reboot yet make sure the update installed the headers and sources for kernel 2.6.34.7-0.4: rpm -qa | grep 2.6.34.7-0.4 should print the files in red on a 64bit system:

I've upgraded kernel 2.6.27.48-0.2-default to 2.6.27.54-0.1.1 on openSUSE 11.1. Before I tried to upgrade to 2.6.27.48-0.3-default where I encountered the same issue. After reboot it can not find the modules for 2.6.27.48-0.2-default which puzzled me to no end. Now I have found that the /boot which is on separate partition of ext2 type is not mounted. The mount command does not recognize ext2 and xfs anymore.
Clearly the initrd does not have the right modules. Since this is standard zypper up process I would expect this to work without issues since it has worked until the 2.6.27.48-0.2-default kernel without issues. Has something changed with the last 2 kernel versions that requires some extra actions from me and if so what do I have to do.
If I can remotely reboot a server using SSH over CGI? I configure the client and server with keys to make ssh without password, and, on the terminal i can make "ssh root@server_ip reboot" and it reboot normally, but, I don't know how to do this on a CGI?

I have a machine I use remotely when I have to travel, some time for quite long periods like from one to three months.
Last time it happened to me that after upgrading I send the reboot command
and the machine didn't turn down, so I couldn't be able to access it.
My question is: how can I avoid such situations?
Is there any best practice to follow?
I searched a lot but can't find a solution. I'm running a root server without access to screen and keyboard and looking for a possibility to upgrade from OpenSuse 10.3 to 11.2.

What is the name of kernel optimized for server machine? In my case Firebird database + Apache + PHP?
A few days ago yast did update my computer to a new kernel-desktop 2.6.31.12-0.1.1.
My mainboard is an ASUS P4P800-VM with Intel ICH5 chipset. This new kernel is not able, to poweroff my computer. Older kernels were able to poweroff the computer.
How can I roll back to the older kernel? Yast does only offer the recent kernel.
In /boot there are only files of the recent kernel.

I just reinstalled my OpenSuse 11.3 with the GNOME desktop. As soon as I was done installing and I was on a fresh desktop, I installed the Yast updates that were available, rebooted, and now I can't login to any of my User accounts. Whenever I try to login, it tells me that it is "Unable to Open Session".o any of you know how I can fix this without having to reinstall all over again
View 1 Replies View RelatedI ordered a SuSE 11.4 installation DVD from an online Linux Distro distributer that I've used before with no problems. I did this rather than burn my own DVD from the website. I thought that I might perform a fresh install of SuSE 11.4 on this Dell 1420 Laptop that is currently running Ubuntu 11.04.
Note, this is a completely fresh install, not a side-by-side installation with Ubuntu; I followed the installation sequence that completely repartitions the entire disk for SuSE, and accepted all of the suggested options regarding logon, etc.
Everything goes well ... sort of. The first install didn't reboot correctly, i.e., the set-up that is supposed to run after the initial install never happened and I had to manually power-down the machine and restart from the "safe mode." Needless to say, that didn't work as expected. So, I re-install, from scratch, trying different options: for instance, instead of LVM, I decide to have an un-encrypted partition scheme and accept the "obvious" options ... thinking that the LVM options interacted badly with the install. Eventually I get the installation to proceed correctly, or so it appears: it goes though the entire sequence, including the re-boot, building the default image, etc.
I test this image by removing the DVD, power-cycling the machine, and all looks good, so I begin the process of installing software updates, etc. Being paranoid, I re-boot the machine, and all restarts correctly, etc.
Now here's the annoying thing. The next day, I power the machine on, and it locks at the splash screen. By the way, these are the exact symptoms that I experienced with the bogus/incomplete installations. The boot sequence proceeds up to the splash screen and waits forever.
So, in sum: I spent inordinate amounts of time attempting to install this software, carefully following the instructions provided by the installer. In every instance, after leaving the machine off for a day or so and rebooting, I am met with a splash screen that sits forever. Needless to say, I am extremely reluctant to repeat another day of software installation to only have to re-start with no assurances of success. Either I go back to ugly Ubuntu (which has always worked out of the box, by the way), or I look at other options. I was hoping to use SuSE, but I really don't care which distro is on that machine as long as it works and it provides TeX, R, Emacs, Scheme, and a few other software packages that I'm sure are of no interest to your customer base.
I just wanted to install openSUSE 11.3 64bit. Installation works fine until reboot request. It switches to console, saying that it tries to load without reboot, screen becomes black, i got a cursor with animated wait-symbol and then it freezes. Can't move the mouse, no reaction on keyboard inputs, HDD-led not blinking. If I reset my PC and boot the new installation, it says that an error occurred and asks me to complete the unfinished installation. It starts auto-configuration and freezes again at about 3%. I tried again and some time it did not start the graphical yast but in textmode. The freeze came at the same position, but it posted many lines on console with error messages. I could not scroll, so I saw only parts of it, saying kernel panic and many addresses.
I guessed that it has to do with my chipset and graphics card, it is a nVidia GeForce 9300 chipset (MCP7A) with onboard graphics. It works fine with openSUSE 11.2 64bit by the way, but it was not supported in earlier versions than 11.2. So I tried to install it with proprietary drivers. I started the installation again and added the nVidia repository and a Packman repo and selected the driver which works fine on 11.2. Error was same as above. Next I tried an openSUSE 11.3 32bit Live CD that came with some PC magazine and lay around and it is booting and works fine!
This was confusing to me, so I wanted to try the 64bit version of the live CD. Which was again not booting. It freezes at some part, maybe when it tries to start X. But it also freezes booting with 'nomodeset' (found it somewhere here), in VESA mode and even in textmode! So i guess it's not X what causes the freeze. But it is sometime at the end of booting up, as far as I can say. I would like to use the 64bit version but I don't know where to search for the problem. I checked every checksum before burning, so a broken media should not be the reason
This system has AMD Turion with ATI HD 3200 Graphics system. Installation program correctly initializes graphics - all installation completes with automatic configuration - gives no option for sax2 to run. Then Suse does not comes up or the x does not comes up or display is not showing anything. I can switch to Vista and Vista boots works from grub menu. How can I test and configure graphics and monitor before installer boots the system?
View 1 Replies View RelatedI am an experienced Linux admin and have been using SuSE for many years. My development machine has had every version of SuSE since '02 and although it is a little old, is in good working order. (AMD
2400, 2 gig RAM, 160 Gig IDE disks - SuSE on disk 2) (OpenSuSE 11.1 with the latest kernel works perfectly. This install is on a spare HDD prior to doing a full install on my usual HDD.)
When I try to install SuSE 11.2 from DVD, the load kernel operation hangs at 97% (using both normal and safe kernel), however, I can install from live CD without any problem. I have tried the same DVD on a few "older" machines and had the same problem. I initially thought it was the actual DVD but re-burning has the same problem. I have also tried another DVD writer - same problem.
I have a system running openSUSE 11.2 with Desktop and XEN kernel, as well as Windows 7 (not by choice though...). I have noticed a strange time issue, with Windows 7 and the desktop kernel the time is correct (like for example now: 1:32 PM) but in the XEN kernel it is ahead several hours (6:32 PM). If it was an issue between openSUSE and windows then I would think that it is a problem with the system clock but I don't know what would cause a time issue between kernels like that.
View 6 Replies View Relateddifferences between Kernel Default and Kernel Desktop? I've found some past threads like this link and this other link, and some other google info, which suggest the only difference would be the io scheduler. Also, I see the default grub choice is "Desktop" and not "Default", so I take this as a suggestion to prefer one over the other.
However, my broadcom 4312 wireless only works on the "default" and not on the "desktop" kernel, so I guess there must be other differences. I just want to evaluate which one is the less long-term risk option to go.
I tried several times to install sue 11.3 on a amd 64 system by configuration a soft raid1 by this order:
md0 /boot
md1 /
md2 swap
or my problem, after configuration and install over the dvd and yast installation menu, after the first reboot I have a grub error -> nothing found.If i try to setup suse 11.2 over the same method, it works.after a system upgrade to 11.3 all is working fine. The only problem is by installing directly the 11.3 I also re-download the dvd and try over the netcd and it's all the time the same error.I searched in the forum but nothing found (perhaps i do a wrong search)
I use the Air openSUSE theme for my panel bar, etc., yet, after rebooting (or starting up the computer after it has been shut down), the panel bar comes up as if it were configured with some kind of black theme, which I do not like - you can still see things like icons for windows, launcher, etc. except for the clock, since its font color is black.
How do I put a stop to this? I have tried everything I can think of, customized settings, different themes, and so on, yet I get the same results after booting into openSUSE.I am using the openSUSE 11.2 KDE version.
11.3 will not load after the first reboot during install, after the reboot the screen just goes blank and that's all.
This is a single setup no dual boot, from openSUSE-11.3-DVD-x86_64, on brand new Latitude E6510 laptop.
config is pentium D and nvidia 7300 , plus 1 gb of ram ; ok they had an 11.2 opensuse version and installed 11.4 from a cd (or dvd) they bought in a shop , the pc is working ok, but upgrades are NOT , how come ? This looks stange to me
- in init 3 : zypper cc && zypper ref && zypper up does not work : after reboot using "shutdown -r now" the pc is frozen, with the green screen and white lizard (no access to keyboard, nor to grub options), ctrl+ alt+ f1 is ko for example.
- in init 3 and only with 3 repos (oss, non-oss, and update of 11.4) a zypper dup works but a bug with mozilla firefox 4 brading opensuse which is ko . we continued , can one package break down a zypper dup ? ( same ko result : after reboot usinf shutdown -r now the pc is frozen with the green screen and white lizard (no access to keyboard, nor to grub options) )
Have openSUSE 11.1 and (AFAIK) KDE 4 on an older notebook; worked OK for weeks, then booting became a problem and the OS seemed to go to sleep between keystrokes: now the cursor stops blinking, the clock stops running, and nothing happens after clicking a radio button until the mouse moves. Am now 25 minutes into a reboot, hung at "Unmounting file systems" but it also hung for a while when changing run levels. Is this related to the stability problems with 11.1 I've read about? Possibly KDE? Where would I adjust a config to use kde 3.5 rather than 4?
View 9 Replies View RelatedI am installing 11.2 on an older machine, Athlon 2800+, GeForce 6800, 1 GB RAM. Install goes fine until try to reboot to the OS and just get massive garbage on the screen. Can't see anything just lines crossing the screen, it seems almost like the resolution is way off but don't know how to change that since I can't see anything. I tried two different install disks to make sure not the problem and got the same thing with both. I tried installing both KDE and GNOME on separate occasions and still same problem. I have used the same install disk to put this on an even older machine and that went fine. I do have windows 7 installed on another partition. I'm fairly new to linux but I'm learning.
View 9 Replies View Relatedin a previous version of openSUSE (I think it was v10.3), there was a possibility to directly/automatically start another OS after exiting (rebooting) openSUSE. This could be done through "right-clicking" on the Reboot (Restart) button from the KDE's log-off dialog and choosing the OS you wanted to be started after the restart. Please, does anybody know if this is possible in openSUSE 11.2 (KDE 4.4)? PS: I know that GRUB enables that, but I prefer a "GUI way" rather than using command line and editing configuration files
View 4 Replies View RelatedI have the problem that for working properly my soundcard needs sort of re-initialisation after every reboot (11.3, 64 bit). I have to change a setting in the sound module of yast that causes the yast to rerun its final steps. What is not working otherwise is audio playback from a usb TV-stick (recording is no problem, same as playing an audio/video file). any idea what might be the problem? how to call the final steps of the sound module of yast from the command line, I could at least put that call into boot.local to avoid having to call yast.

I hope I open the thread in the correct section.I have just installed OpenSuse 11.4 with XFCE environment on my Acer Aspire 5738Z.Everytime I boot, I experience the following "strange" behaviours:1 - I need to reconfigure manually the "capture device" with Alsamixer to change it from "micro" to "internal micro". Even though I restore a taylored asound file with alsactl, as I used to do when I used Ubuntu, every time I restart my computer, the capture is on "micro" again.2 - In the panel, I need to remove the Thunderbird launcher. I remove it everytime I log in on Suse, but it comes back after every reboot.3 - Skype and Pidgin start automatically, even though they no longer are in my list of apps to start automatically after log in. (They once were, but then two instances of each tried to start at the same time).Besides, I have another problem with the action button, the one that enables to shut down, restart, hibernate, etc. When I click on it, I will immediately be logged off.
