Ubuntu :: Did Karmic Install Two Kernels On Your System?
Apr 13, 2010
After I upgraded Jaunty to Karmic, I found that my grub menu has two pairs of OS options and that the kernel is slightly different between the two. The highest numbered kernel seems to be a working OS release but the next choice in the list does not work correctly - its mouse pointer is invisible!I originally had installed Intrepid in a partition and I used it for a while. Then I decided to upgrade to Jaunty so I put that release in a different partition. I had major troubles getting the system going after the upgrade but I eventually succeeded.Later, I decided to try out Karmic so I created a Live CD of it and tested that. It seemed to be good so I decided to do a standard upgrade. At this point I still had the original Intrepid version on disk in its own partition. The release notes suggested that a network upgrade was the preferred way to upgrade to Karmic so I did that, even though I had the CD. The process seemed to complete OK. I was getting some X windows complaints and X was running in low graphics mode so I uninstalled and reinstalled the fglrx driver; X was happy afterwards. That seemed to be the only significant problem with the upgrade.I noticed that my grub menu now had three fairly new selection pairs, as well as the memtest and the original Intrepid software. I had gained two pairs during the Karmic upgrade. I could not tell which was which by the kernel numbers. I decided that three sets were inappropriate and I decided to remove one set. I was hoping to remove whichever set was superfluous or unnecessary. I picked the oldest of the three (i.e., the one with the smallest kernel number) and used Synaptic to abolish it.
Now, I had two pairs left. The topmost pair is a working Karmic version which I am using right now. The other pair seems to be a broken version of Karmic. By that, I mean that it starts up exactly the same as the working version but when it gets to the login screen then there is no cursor! Actually, the cursor is there but it is invisible. I found that I could run the cursor all the way to the top right corner, click the left mouse button, and get the shutdown/restart/etc. menu. The keyboard's arrow keys could then be used to select a menu item and the mouse button would activate it. But all the while, the cursor was invisible! Of course, this makes the system useless.So, I think that I need to use Synaptic to remove the malfunctioning pair. Questions: why did the upgrade give me two kernels? Would it be safe to remove the earlier one?What I would really like is to have both Karmic and Jaunty available from the grub menu. I am afraid that I will have to do a new install in a different partition to get Jaunty back onto the system, and then will have to repeat all of the customizing and software installations that I have applied during the last year or so. Does anyone know of a shortcut around that?
I can't find the place to set the system to keep multiple kernels. For the first time in a long time, updates are giving me grief. I've kept the last working nvidia driver in case I need it.
Now I would like to keep one old kernel when I update to the new one. I had a lab rat that never got rid of old kernels and that was too much. It is possible to keep the last working kernel when you update, isn't it?
I have had a new install of Karmic from CD and have done all updates and added a few applications like VLC and a few others. I have several different media players, Totem, VLC, Xine, and gxine. I started out thinking Totem might be enough, but added VLC as it can handle just about anything, and then the other just to see of any thing happened.
I have installed all restricted and unrestricted packages from the Medibuntu depositories I can find. Still my laptop will not read any kind of DVD. I am region 2, but have tried both bought region 1 and region 2 DVDs. I had this problem last time I installed Ubuntu, but after installations of a few applications and messing about it suddenly worked. I really didn't know why or what suddenly was working.
Take Red Hat Enterprise Linux for example, it has U1 to U5 editions, and each edition supported several kernels, like U5 supported 2.6.18-194.el5PAE, 2.6.18-194.el5xen and 2.6.18-194.el5.
How can I know all the kernels supported by each edition of various Linux distribution? Like all the kernels supported by Red Hat Enterprise Linux U3 or Debian 5.0, or SUSE 11. Is there any websites providing such information or I have to log in their official site to look for? And how can I be kept posted with such information?
Couple weeks ago my automatic update did not finished properly. It crashed (I'm not sure about the reason). Since then, I'm not able to see installed new kernels in my computers. I can see them in Synaptic package manager as installed but I do not see them when I reboot. I would like to see them and try them.
Installation used default options. Discovered that my "standard" Desktop kernel isn't likely PAE enabled... Have had various FF windows open for a long time even with no network connection which resulted in memory leaks (understandable). Eventually the machine slowed to a crawl with numerous FF processes running (each about 8% of CPU) and 4GB memory map (4GB physical RAM) exhausted but surprisingly the 2GB swap was totally untouched. Searching the Forums there are numerous anecdotal opinions that PAE should be or was enabled automatically at least for Desktop kernels. Viewing the OpenSuSE repository, there are kernel-pae packages for this kernel version which aren't installed.
So before I start installing packages willy-nilly, is there an authoritative published source that documents what is is in an OpenSuSE kernel package, and what combination of packages plus if necessary additional manual configurations to achieve desired goals? BTW - I'm somewhat surprised that today PAE is not automatically included in today's kernels considering how cheap hardware is... I don't know if PAE typically should be a noticeable performance hit on low resource machines(like netbooks) and would be necessary for anything configured with more than 4GB total (physical plus swap) memory.
Is there a description of the features and differences between the Desktop and Default kernels? Did "Desktop" arrive with 11.2 and 2.6.31? I did not notice it at first. I loaded 11.2 on a desktop machine and both default and desktop kernels were loaded to system, with Desktop set as default in grub. I have been working thru several "strange" behaviors ever since loading 11.2. At the top of my list has been the ability to shutdown the system from remote logins. I normally connect to the system via a Xwindows package (Xmanager). X works fine and I could shutdown via the GUI (Application Launcher - Leave-Shutdown).
When connected via a remote ssh link, either from a windows machine or a different linux machine, attempts to shutdown (shutdown -H now) send the expected messages, close the remote connections but leave the system still powered on but in a no-remote-connectivity state. When I upgraded to KDE 4.3.4 following the Forum Repository guidelines, I could no longer shutdown via the GUI. In searching about, I found that the Desktop kernel was running. Changed grub, rebooted under default, shutdown under GUI works again. So, for starters, I am trying to decide which kernel environment (default or desktop) should be my target for continuing to work thru issues.
Are there any official, almost-official or maybe even reasonably stable kernel repositories with new kernels for opensuse 11.2? I recently changed my laptop for a new one which has some issues, which then again are solved in 2.6.33 (and even in 2.6.32 with some tweaking). I would by any means try to avoid kernel recompilation.
Has somebody used DAFS (Direct Access File System)?I've found a lot of literature about this file system,where the comprassion tests promise a ~20-50% faster packet transmission,than in the strandard NFS.But I can't install DAFS,because the source code is for old kernels 2.4.Does anyone know,why did the research of this file system stopped in 2003 year,and there are no newer versions?
i use Fluxbox (Mint in Karmic, but after few tweaks and updates i have to reinstall system-but i couldn't even make with gparted and usb-creator startup disk, so i used virtual machine in Mac OS to make some older version (Mint 7 XFCE).BUT, then i discovered that i can not even load the system from USB-although it was all set in bios to startup with USB Stick. How can i persuade my dell mini 10v to start up from live USB Stick.
I like the system beep because I can tell checkgmail to beep when an email comes, that way my speakers don't have to be on.Anyways, I did a fresh install of Karmic the other day. Something is being weird with me when I try to re-enable the beep. Karmic blacklisted pcspkr in /etc/modprobe.d/blacklist.conf . Here's what happens:I leave "blacklist pcspkr" in blacklist.conf and restart. I do "sudo modprobe pcspkr" and then "beep", and it beeps. Good.
Then I comment out "blacklist pcspkr" in blacklist.conf and restart. I do "beep". Nothing. I do "sudo modprobe pcspkr" and then "beep". Nothing. I do "lsmod | grep pcspkr". It's listed there as it should be. I check with "sudo grep pcspkr /var/log/dmesg" and find no errors.
it has been a year since I've started using Ubuntu linux, and for being calm that everything is working properly, I would like to do a full system check. The only option I've found is on System=> Administration=> System Testing, but this wasn't what I was searching for (mainly because I don't know what is written there- I don't know enough for running this option). Is there something else I can do? maybe something through Terminal?I want to run such a check also because the system sometimes work slowly, and maybe something went wrong...
A local store built a brand new dual core system for me about a month ago with a 1TB drive and installed Karmic on the entire drive. I now have a piece of external hardware that requires XP and simply will not work in XP in Virtualbox. I have purchased another 1TB drive, and my thinking is to create an XP partition of about 2-300GB and leave the rest of the drive for another Karmic partition and dual-boot. I don't care which drive is primary (unless there is a reason I should).
I was thinking of unplugging the karmic drive and putting the new drive in it, installing XP on it, then adding the Karmic drive back to the system and editing one of the boot files to add the other operating system.
If so, which boot file should I edit? Which drive should be primary? Or, is there a better, easier way to do this?
I have the System of 9.04, but have a Live CD of Ubuntu 9.10 too. But, I do not want to download all the massive Upgrades. Still, Ubuntu 9.10 is the best! So, can I upgrade 9.04 to 9.10 using the Live CD? (Offline).
My Ubuntu Karmic running system experiences random lockups. There is no pattern in when it will happen, it can go for days without one, or happen every couple hours. Only thing I can notice is that it happens most often when I run Firefox, but when it happens, it happens regardless of me having Firefox open on a website with lots of Flash content or not. When the lockup happens, I cannot move the mouse - the led light on my mouse shuts off, I can't move the cursor, the whole UI becomes unrensponsive, there is no blinking lights on the keyboard, REISUB does not work, only hitting the reset button on my case helps. After reboot, there are no indications of errors in any of the logs that I can see.I have ran memtest for 24 hours, and it completed without errors.

Last Monday I upgraded the Ubuntu from Karmic Koala to Lucid Lynx in my laptop (HP Compaq volna 515), and I have no sound. Searching in linux forums for an answers, I've got that (as far as I understand) there's no unique solution for this problem.
This is my lspci code...
Also, I tried to clean up the pulse audio .. What is funny for me is that pulse audio and alsa, and the audio players seems to work normally (no error of device not found or something like that).. except that there's no sound out from the speakers.
Any suggestion to discover if the problem is drivers, kernel, packages, or hardware failure? more important, how do I get the sound back?
I've never had any use for IE, all the browsers that run natively are just fine. This is the first time I've actually needed it -- I'm applying for a job that happens to be on an IE only website. (Sofrustrating) I've tried many approaches to install Internet Explorer through wine and have failed so far. Everything I've read seems to point towards ies4linux. I attempted this:
Code: wget http://www.tatanka.com.br/ies4linux/downloads/ies4linux-latest.tar.gz tar zxvf ies4linux-latest.tar.gz cd ies4linux-*
IEs4Linux 2 is developed to be used with recent Wine versions (0.9.x). It seems that you are using an old version. It's recommended that you update your wine to the latest version (Go to: winehq.com). So I removed wine and installed version 1.0.1, which resulted in the same error. Is this wine version too new? even if it doesn't involve ies4linux.
I just recently upgraded from Jaunty to Karmic and now I can't seem to get the nvidia drivers to work properly. It originally came up in low graphics mode and said that the 190 driver was installed, but it didn't work properly so I disabled it.After rebooting, the 190 driver will never properly activate. I tried launching jockey-gtk and it tells me to see /var/log/jockey.log which shows:
2010-05-16 08:54:58,054 DEBUG: Installing package: nvidia-glx-190 2010-05-16 08:54:58,778 ERROR: XorgDriverHandler.enable(): package or module not installed, aborting
I wasn't able to get the 185 drivers either until I did a manual apt-get install nvidia-glx-185. Then it eventually worked and nvidia-xconfig got my xorg.conf updated and correct. So now the 185 drivers are installed (though jockey-gtk does NOT show those drivers in green -- it doesn't think that I have any of the drivers enabled so all of the little bubbles show up as grey). The 185 drivers are definitely installed though (185.18.36 to be exact) and Compiz is enabled, desktop effects are on, etc.
Any idea what is up with this? Why doesn't jockey show the drivers that are installed and more importantly, how come I cannot install the 190 drivers? I tried doing it via apt but this is what it tells me:
$ sudo apt-get install nvidia-glx-190 [sudo] password for bdmayes: Reading package lists... Done Building dependency tree
This was my first attempt at compiling a program from source. Maybe I should have picked something easier but I am trying to install gutenprint (formerly gimp print)so I can use my new Epson scanner/printer.Should I remove this thing and start over?
I dual boot on separate HHDs. I have just done a fresh install with updates. I installed the restricted driver from the repositories, and I get an error message from ati catalyst (administration). Also I have "unsupported hardware" at the bottom of the screen.
Graphics card is a XFX ATI HD 5770 on this system, and I just sold 2 8800 GT's yesterday, and bought two more XFX HD 5770's for CF in my other system.
I didn't do a bad thing, 'cause I was really groovin' on Ubuntu, that I just installed at the beginning of the week.
