I've done the usual edit of /etc/sysctl.conf to include the parameter, but it just tosses errors. I haven't had to tune a kernel in a very long time, what's different about it nowadays (or have I simply forgotten how)?
edit: Added "kernel.semmni = 2048" to the tail of /etc/sysctl.conf and then ran "sysctl -p". End result is an unknown key error (apparently kernel.semmni isn't the valid name anymore?).
I set the default os to boot as windows 7 with a timeout of 1 second. I thought that this would be enough time to switch os ubuntu when i need to, but I am unable to. How can i reset the timeout to 3 seconds? I also cannot view the ubuntu partition within windows because of ubuntu's file system.
Since certainly half a year I have to add the vga=0x317 parametere at the end of the root parameter in the menu.lst file after each upgrade of the kernel and also recently after upgrading from 11.1 to 11.3. Without this, the splash screen is not shown on my HP Pavilion laptop.
Suffering from the expected error in detecting my video properly when installed 11.3.Have intel 915G onboard video. Up until 11.1 Opensuse struggled with loading this correctly. in 11.1 & 11.2 all was well. A couple of minor tweaks in sax2 and it worked perfectly. Now hat sax2 has gone I'm not sure how to make these minor tweaks.
My problem is I have been forced to a screen resolution of 1024X768 VGA Following the readme file adding nomodeset at boot fixes the problem but of course forces me back to an old video driver with pretty poor performance. Is there any way I can change the screen resolution and set the correct monitor - any GUI replacement for sax2? Krandrtray will only let me set a max res of 1024x768. I need to set res to 1280x1024
where the time to display media notifications is stored? When I put a CD or DVD into the player slot, a popup window shows possible actions to take but these old eyes can't read it fast enough to get through the list. Is it possible to get it to display longer and if so how?
When I put an audio CD in the slot, the display says there are six (6) actions possible but I only have time enough to read the first 2 or 3.
I ran into a problem the moment i installed 11.1. The GUI wouldn't show up (ctrl+alt+f2 yeilded a black screen with a blinking underscore). Failsafe worked fine, though.
So, i tried entering, one by one, every parameter that was entered in the failsafe boot options. Entering 'x11failsafe' gave me a flawless GUI. So, i opened the '/boot/grub/menu.lst' file and added this parameter in the 'showopts' of the normal mode, to make it permanent. Fine. Now, what exactly have i done?
Note- I use an NVidia 8000 series Graphic card. I'll post more details if you need them.
I want to use secure file permissions within OpenSUSE, but having to provide the root password for every window I click is just a little too much.Wonder what the setting "paranoid" does then. And I also wonder how to adjust the safe settings to not get prompted with every single click.
I am having a problem with my touch-pad on my Dell Inspiron 1525. It needs to be adjusted for speed and it starts scrolling unexpectedly. I understand I need to install a driver for it but don't know how. The problem I see with Linux is that it's not easy to install software for new users. I have ran into a few One click Installs and managed to work them out quite easily. Usually the documentation you find online to install programs assumes the end user knows how to install.I need to know how to install the touch-pad driver from start to finish and all steps in between.
The installationen freezes the moment when the Setup comes to Adjust the Timezone.I have already tried all other Installoptions (Secure Kernel, without APCI/ACPI), no difference.I tried the Install-DVD on another Computer (on which i dont want to use Linux) and it didnt crash at this Installationstep, so the dvd seems to be ok.My System is a AMD Athlon XP 1700+, 256MB RAM, which should be ok for Minimum system requirements
I have a new Dell Inspiron 1545 with a dual-boot setup: Kubuntu and Windows 7. A long, tedious story made short, I have Kubuntu working but cannot for the life of me get the wireless adapter to work in Windows 7. Since the Microsoft universal fix consists of reinstalling the OS, that's what I plan to do.
That said, I'm concerned that Windows will not just reinstall itself, but wipe out the boot record used by grub. I've invested enough time setting up Kubuntu that I really don't want to start from scratch (again) with both OSs.
How to reinstall Windows without wiping the boot record? If not (i.e. Windows will kill whatever grub has in place), is there a way to use the Kubuntu disc, or another linux disc, to reinstall grub afterward, thereby leaving the linux partitions intact?
Since last last week i've installed Windows 7 and OpenSuSe 11.2 linux several time in my laptop. Each time i do something and Linux boot menu disappears and i again install both operating system. I have installed linux for the first time 6 days before in my life.
I am trying to live without windows. I know i can't for more few months as there is problem in every step for me.
Now i have both os running perfectly and boot menu appearing perfectly.
There are 3 partitions in FAT32 created while installing linux for Windows files. Now i want to change it in to NTFS. All drive are empty.
##1 Is it ok if i reformat it in windows 7 and change to NTFS?
##2 Does it creates problem in GRUB boot menu?
##3 Is there any way to do this from Linux without any problem?
##4 Is there any way to change FAT32 into NTFS without affecting GRUB?
I'm tired by installing again and again. I don't want any more trouble for next 1 month.
I had Windows Vista Business in my compaq presario CQ40-145 TU laptop, over which I installed Fedora 13, making the system dual boot. The Windows is set to be the default OS. Now I want to replace Vista with Windows 7 professional without affecting Fedora. As far as I understand, during boot up, the system enters Fedora's booting process and then gets redirected to Windows, and it is not directly windows even if the default OS is windows.
The reason behind not disturbing fedora is the updates, extra software and packages installed and the pain and time it took me to make my speakers, wlan and flash player work in it. I even don't remember the exact process of what I did. I don't have now so much time to search for it again. So I will take up only that way in which Fedora is not affected at all. And the second problem is my DVD drive is not working at all. So I'll like using USB stick for the same.
I've been running 64-bit openSUSE 11.2 since shortly after it's release, on a quad core AMD Phenom based machine, using KDE as the Desktop. I have a USB-attached "multi-function" printer/scanner/etc., which worked fine with XSane under 11.1. On the same machine, with 11.2, I can still get a scan preview. But when I try a full scan, shortly after it starts, the progress bar stops, then XSane complains about an I/O error.
When I update openSUSE versions, if I can, I keep the old version completely intact, on the same machine. This includes the /home partition, I don't overwrite it. Sure it's a good deal more work to copy over the numerous files needed, but if there are any problems with the new software, it's extremely helpful to have a completely intact old environment for reference. I was able to do this, while updating 11.1 ==> 11.2. Booting the old 11.1 system on the same machine, I haven't encountered any scanning problems.
I haven't given a lot of details, because it's the same hardware, that should "in theory", mostly eliminate the hardware as a possible source of the problem. I'm hoping the problem can be resolved by focusing on any changes in SANE support, or XSANE itself, for USB attached scanners. It could be unrelated, but messages such as these are in /var/log/messages on the 11.2 sys:
Feb 3 17:45:03 toe-heaven kernel: [ 5881.313532] usb 3-1: usbfs: interface 0 claimed by usblp while 'xsane' sets config #1 Feb 3 17:45:03 toe-heaven kernel: [ 5881.313560] usb 3-1: usbfs: process 8214 (xsane) did not claim interface 1 before use
If XSane is doing things in the wrong order, I'm wondering if it would be a problem especially for a combined printer/scanner, or would the problem still occur if the printer and scanner were two physically separate devices? I checked and there are similar messages in /var/log/messages with 11.1. But if it is an error in the sequence in which XSane does things, could it somehow cause problems under 11.2, yet not 11.1? I tried to find anything which might be related to USB device handling, which perhaps could interact. I came across messages such as these in 11.2, but not 11.1:
Feb 4 15:15:10 toe-heaven udev-configure-printer: add /devices/pci0000:00/0000:00:02.0/usb3/3-1/3-1:1.0/usb/lp1 Feb 4 15:15:10 toe-heaven udev-configure-printer: parent devpath is /devices/pci0000:00/0000:00:02.0/usb3/3-1
Is USB printer handling somehow different under 11.2? With a combined printer/scanner, could there be an interaction? I did some experimenting. I kind'a thought a scan preview was just a scan at low res. So I tried to do full scans, starting with the lowest res., and increasing. I was able to do successful full scans at 100 or 150. But from 200 on up, the higher the res., the shorter the time to get an I/O error. I'd normally use 600 or above, to get what I feel is a good looking scan. At 600 the error report is practically immediate. It's almost as if the error only occurs above a certain threshold, of amount of data per unit time. I should mention, although it's a color scanner, I'm scanning a black and white doc., so using that mode of XSane.
Goal - have Ubuntu on one HDD and Win 7 on another. Sub-Goal - get rid of GRUB without adversely affecting Ubuntu install .I have three HDD's on my system; one contains Win 7 Pro (no complaints, love it), one is for storage (NTFS) and the third has Ubuntu on it (aside from the wireless issues and DVD playback issues, I love it as well).
All three drives are internal, but the Ubuntu drive is a special case. It's installed in a cradle that resides in an external bay. The Ubuntu drive can be turned on and off at will. I don't need GRUB (which will only confuse my fair lady).
So, if I run Win 7 recovery and "repair" the mbr, what will that do to the Ubuntu drive (which will be set as the first boot device in BIOS)? Will it boot per normal when the cradle is powered up, or will it be looking for GRUB?
I am following an instruction on the Internet to set up a timer=1. "You can force use of the timer interrupt by using the timer=1 module arameter (or oprofile.timer=1 on the boot command line" When I type "modprobe oprofile timer=1" at the command line, I got a warning message saying that "Deprecated config file /etc/modprobe.conf" So i want to try other way by setting it at the boot command line.
I would like to adjust Xinerama to place 1 desktop on each of my 2 monitors and not stretch a single over both. With the current set up there is a problem with window placement upon opening new widows or context dialog boxes. I realize that I could adjust placement properties and select window placement with the mouse but this is still lacking in productivity. My monitors are not next to on another so this is more of a problem than it seems.
Im trying to instal Sun Virtualbox but when download completes and I click on install I get the following error>>Message did not receive a reply (timeout by message bus) I wont even bother with this software if there are others out there that are as easy to use. I used it on Windows and thought it was great ! (thats how I eventually switched to Linux, by using it virtually at first)
First off all, I'm booting from a large MEMDISK using PXE (900MB) . Due to our environment, I cannot decrease the size, nor move files to a nfs/iSCSI/... environment. Everything needs to be in that MEMDISK.
Now, when I try to run the OS, I get out of vmalloc space. How do I increase it to a number which allows such a large image to be mapped? I tried the parameter "vmalloc=1280M", but with that parameter, I don't get past the Booting the kernel screen.
Memory should not be an issue, since the machine(s) have at least 2GB RAM. (900MB MEMDISK + 256MB for other kernel stuff + 768MB for user stuff). The machine(s) have a Pentium 4 Extreme Edition processor, with hyperthreading and SSE2, but no EM64T.
How can I boot the system, and get past that message? Decreasing the MEMDISK size is not possible too. It is at the smallest we can get with our userland + kernel + modules.
I just want to know how to adjust the screen resolution of my boot up screen. My PCs maximum resolution is 1366x768 but I think my boot up screen only uses 600x400. I doesn't look nice for me. The logo of Kubuntu is too big and the colors are not the true colors of the Kubuntu Boot up screen.
It's documented in the howto's that you need to have the nomodeset kernel parameter specified if you want to run the proprietary Nvidia driver. But I read in certain posts that this is only required for "older" graphics cards.Can someone shed some light on this? Is the parameter ALWAYS required when running the nvidia driver, or only for certain graphic cards?
So I'm dual booting Windows 7 and Lucid. Thinking I might shorten the timeout for the bootloader (I apologize if my terminology's off), I ran bcdedit and changed the timeout to 0. Little did I know this would prevent my computer from booting into either operating system.
I've got Lucid running off a live cd now; does anyone know how I could change the timeout back from there (or any other way!) and get my laptop working again?
I have a problem to boot from a SATA disk. The filesystem image was created by our customer and copied to the SATA disk. It is SLES 10.2. When booting, "waiting for /dev/sda2 to appear" appears. The filesystem seems not to be corrupted, it can be mounted via a live CD. Here are the files I consider being useful for you.
I'm trying to install Oracle DB on OpenSuse (is it smart, because it's not certified for that OS?)..and I've set oracle parameters using oracle script, but when I'm runnign through oracle installation, kernel parameters check reports that parametersa are 'n/a', like oracle OS account cannot access those parameters..
After setting the "nomodeset" kernel parameter, to install the nVidia proprietary driver in OpenSuSE 11.3 (I need to do CUDA development), my Sansa Clip+ is no longer recognized. When I turn the "nomodeset" option off, I can see it with $(fdisk -l).
I installed last ubuntu from windows 7 using wubi and it worked great, i am writing this from ubuntu. The problem is I changed the timeout to 0 on windows 7 startup options as well default operating system to ubuntu, so now i cannot boot to windows because the windows 7 boot manager just flashes and goes directly to the grub boot manager and even if try to choose windows 7 on grub boot manager it only goes back to windows 7 boot manager and the same thing happens.
I have no DVD drive and i only have a 1Gigabyte USB PEN.
I already searched insanely on ubuntu forums, used unebooting, tried creating a windows 7 startup disk with unebooting, tried formating USB PEN with GLParted and choosing FAT32, ex3, NTSF as well with boot flag and then copying files to usb, wich didnt work. I tried to fix it with SUPER GRUB DISK didnt work too....
Is there anyway i can change this little timeout setting from windows 7 boot partition (yes i really learned something) so i can boot to windows 7? By whatever method, it can be from within ubuntu or using a 1Gb pen?
I know it can only be changed using bcdedit.exe but not even with wine it worked.
