I installed Matlab in Ubuntu 10.10. I was able to get it running and I saw the initializing screen. However it showed me an error with OpenGL
"warning : could not query OpenGL"
and it freezes there. I tried many things to get over with it and it didn't work.
I had ubuntu studio installed ( for the record I hated it and every ubuntu flavor I have ever used. ) After backing off all the stuff from my home dir I started to install testing from a dvd. ( Is there a net install for testing? I couldn't find it) Don't ask me how it happened but some times I would have two grub graphical boot menus. One would chain to the other. I suspect that happened from one of the very friendly updates ubuntu did. Well when I tried to install testing I got a red screen telling me that grub wouldn't install so I tried lilo. Well it wouldn't install either. Back in the old days when I was a slackware guy installing from a stack of floppies I had a trick to wipe out any boot loaders or other stuff that gave me a problem. I would dd if=/dev/zero of=/dev/<drive info such as hda with no partition number> .
This would write zeros over the drive and it would look like a new drive. So I did this trick. But still no joy ( this is a clue, dd was also thinking that the beginning of the drive was after the boot sector.). I suspected that the installer wasn't doing it's job right. So I got a PCLinuxOs disk and started that installer. The PCLinuOS installer has a cutesy visual bar that shows the partitions. Well sure enough the boot sector showed as blank. This was what the Debian installer had done. It left the boot sector blank and tried to install the boot loader right after it. This won't work. Now I consider when some version of Linux falls on it's face and another version does it right that the version that fell on it's face has a problem.
One might even call it a bug. But I don't know what to do about it. I don't think the problem is with grub or the installer itself. I think how the drive was looked at was faulty. That's why dd didn't blankout the boot sector. So what do I do to help get the Deb people to fix this? The more I think about it the more I think the problem is with udev ( what a surprise) I think this because I suspect dd looks to the info set out by udev to find the beginning of the drive.
I burnt the Ubuntu 9.10 ISO to CD and installed on a freshly nuked Dell 2350. It is pentium 4 at 1.8 MHZ with 512 RAM. Just a spare machine I have sitting there. Install went fine, restarted box, boot from hard drive. I get the little white Ubuntu symbol on a black screen and then a black screen with un-occupied white tool bars at top and bottom of screen and a functional mouse pointer, then nothing. It freezes there.
If I restart by holding the power switch in it occasionally shows multiple CPU overtemp messages and freezes with totally black screen. I can run the CD live and everything works like a champ. I'm going to like Ubuntu once I have this sorted out. If I boot from CD and choose the run from first hard drive option, everything loads and works fine. I was able to remove CD, update and save preferences, etc..
On one occasion, I was able to restart and boot from hard drive and it worked fine but usually it freezes at previously mentioned black screen with white bars top and bottom with mouse pointer. Please excuse my ignorance as I have very little knowledge of the inside workings of computers. I didn't even know about burning ISO's or changing boot orders until reading online. For what it's worth, the computer worked fine with no known hardware problems when it was running XP. It also is completely stock with no mods or added/replaced hardware.
I just upgraded to 10.04 through the Update Manager. During the updated however I got an error telling me that it was unable to install something. Sorry, I can't remember what it was; it didn't stop the updated so I assumed it wasn't that important. Anyways, I don't know if this is because of that error, but during the boot process and when shutting the computer I get console messages. When I boot it tells me that "mounting none on /dev failed No such device" and when I shut down I get these messages.I see this was asked before and that it isn't a big issue, but I'd still like to solve it. The problem is that I'm pretty new to Ubuntu and Linux in general I don't know how to follow the very general instructions given in that thread.

The batter drained several days ago, and now when I attempt to boot I simply get a string of indecipherable error messages which last for about 5 minutes, and the screen then goes completely black. I am not able to even get to the login screen. Windows 7 Starter boots fine, so it's definitely a software issue. Any solutions short of completely reinstalling? I really don't want to lose all of my data.

Last night when I turned on my lap top (5 year old Acer TravelMate 4650), it was not able to boot up (10.04 LTS). No system files could be read and a lot of error messages was displayed. In fact, it has done a few checks for disk error lately during boot up, but no further warnings given. I gave up recovering, and simply re-installed Ubntu 10.04. I was wondering if this could be related to a virus attack?

I can get to the menu where I select to check disk, install, try without changing etc... However when I tried to check the disc integrity I saw the Ubuntu logo for about ten minutes and then let it sit for another 20 minutes, and all I saw was a blank screen. I then tried making another CD and came up with the same results. I then tried to install and at first it was like before, but then i started getting different error messages the majority had the form: [ 771.744543] Buffer I/O error on device sr0, logical block 337015another looked like:[ 1244.029631] end_request: I/O error, dev sr0 sector 673592a few said something about SQUASHFS.I have tried three different CD's I looked at the hash and they matched up so the file is fine.

View 1 Replies View RelatedCould not calculate the upgrade An unresolvable problem occurred while calculating the upgrade:
E:Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.
This can be caused by:
* Upgrading to a pre-release version of Ubuntu

The system asked me to reboot and I just shut down the computer.Some hours ago, I wanted to start the computer and the system halted after the first logo showed of Ubuntu, after 15 minutes waiting, nothing happened. I tried to push keys on the keyboard, nothing helped (I even couldn't put on CAPS or num lock on the keyboard).After a secoind reboot I didn't even saw the Ubuntu logo. When there's a black screen, it just sits there.I have no idea if there was a kernel update (I assume there was, because the system wanted me to reboot)
View 6 Replies View Relatedi had a working multi-boot system, vista on sda1,2; swap sda3; ext=sda4; ubuntu sda5; fedora sda6; data sda7 - i mount the data partition when using all of the linux releases so i don't have to have multiple copies of music, docs, etc. everything has worked fine until yesterday. i tried to install fc12 on sda6, replacing fc11. it required me to format sda6 as ext4. i wasn't sure where i had grub installed, but have a backup of menu.lst in data (sda7), so figured i could let it install to mbr or wherever it wanted to by default. when the install completed and i reboot, i get a black screen and these messages: CLIENT MAC ADDR: 00 19 XX XX XX GUID: XXXXX PXE-E53:
No boot filename received
PXE-M0F: Exiting Intel Boot Agent.
No bootable device -- insert boot disk and press any key I tried reinstalling fc12, same exact errors. I then thought maybe the problem had something to do with ext4 partition mixed in with ext3's, so i installed mepis on the sda6, and let it write grub to mbr (i think, not really sure where it wrote it). anyway, i still get the identical black screen. no grub type menu or anything. the screen used to show "DHCP for a few seconds", but doesn't anymore after i disconnected the ethernet cable.........
I followed the guideline 'How to use PreUpgrade' to upgrade F14 -> F15. What happened was that after reboot: 1. The screen was a mess ... no readable information 2. No reaction on pressing 'return' 3. The disk led showed no activity, so I reseted the computer after 5 minutes inactivity. The system came up but with F14. I repeated the 'preupgrade' and all messages are in [URL]... but still F14 comes up after reboot. Where have I missed ... eager to get F15

View 5 Replies View RelatedMy script looks really crap and messy, the logic isn't great and I'm not hugely happy with it. Also it echo's $i instead of an actual IP address (line 10). How to improve this. It basically searches through /var/log/messages for multiple FTP hits and when the hit count is higher than a specific number the IP is added to a config file and ftp is restarted. There are some obvious flaws in my script.
Code:
MAXHITS=0
TOPHITS=`grep "FTP session closed." /var/log/messages* | awk '{print $7}' | sed -e 's/^.*[//' -e 's/].*$//' | uniq -c | sort -nr`
HITNUMB=`echo $TOPHITS | awk '{print $1}'`
IPHIT=`echo $TOPHITS | awk '{print$2}'`
HIGHIP=`echo $TOPHITS | grep $HITNUMB | grep $IPHIT | awk '{print $2}'`
if [ $HITNUMB -gt $MAXHITS ]; then
for i in $HIGHIP;
do
echo $i
sed -i '78s/$/,$i/' /opt/etc/proftpd.conf
/root/ftp restart
done
else
echo "not greater than $MAXHITS"
fi
I'm not even sure what will happen if I get multiple responses for my $TOPHITS. It would be cool if it could search for IP's already blacklisted somehow, it might actually be easier to just create a file with a set of blacklisted IP's or something.
I recently downloaded and installed Fedora 11 Alpha. I then installed the Nvidia drivers for my Graphics card (GeForce 7800 GTX). I discovered that Fedora 11 is using a Beta version of Xorg and an incompatible ABI. So, my drivers would not work with Fedora 11 without me dowgrading the Xorg server. I decided to reinstall Fedora 10 instead.
I started the install, and when the installation loaded the generic video drivers, my screen showed only a bunch of colored vertical lines. Fedora 10 doesn't allow me to install in text mode.
When I do the routine updates, which come every few day, I get the following message.(Please see the attached image.)

I have tried a fresh install with a disc I burnt and ran with my external dvd drive. Well guess what it decided to not boot from it. I have also tried several other discs including a windows xp disc. it always boots back to the hard drive.
i installed the new beta 10.04 and it seemed right after the install and update that both nvidia hardware drivers were automatically install together. i deactivated both drivers. one driver showed the nvidia 173 driver and the other one showed "current" nvidia driver.
after a restart i then tried to activate the 173 driver. system required a restart. so i did. system booted to a black screen. i believe its at the desktop but i am unable to see it. i tried to hit esc at the boot screen to enter the grub menu but that didnt work.
I'm currently running Ubuntu 9.10 on my server and I want to install a new 10.04 from scratch in a second bootable partition to be able to boot it up and test the new version before putting it into production (without tampering with my old version). I have an empty partition on my drive already
View 2 Replies View RelatedI recently tried installing Lucid x86 on my system beside Windows 7 and managed to screw it up.
My disk setup is this;
Disk A = 3 partitions (1st partition=Windows 2&3 partitions=Data)
Disk B = 1 partition
Disk C = 3 partitions (1st partition=Data 2&3 partitions=Ubuntu & Swap)
Disk A = SATA and internal
Disk B = SATA to USB external
Disk C = SATA to USB external
I want to install Lucid on the 2nd partition on Disk C. And dual boot it with Windows on Disk A.
During Lucid setup i specified the partition for installation (C2) and asked for GRUB to install on Disk A (no partition specified) so GRUB is always used as the dual-boot manager even if the Lucid disk (Disk C) is ejected. Once installed and rebooted i was taken to the GRUB rescue prompt as no installation drive could be found (a long string of numbers (looked like a Disk ID number???) was also shown). Obvviiusly, i could not access either OS on my system at this point. I had my W7 DVD handy so it was just a case of recovering the windows boot manager and i could use my PC but how do i go about installing Lucid with this setup? Should i specify a partition for GRUB to install to? I have a hunch this is where i am going wrong but am too scared to try again and potentially balls things up.
I currently am in an adventurous phase and want to try other distros while still having a reliable, stable Ubuntu installation to fall back on. I'm currently in the process of partitioning my disks, and I realized that I might have trouble booting them, as the most recently installed would control GRUB and clobber any previous GRUB setup. So what I want to know is how to go about managing everything so that only one distro, preferably Ubuntu, has control of the GRUB menu at boot up, and will still recognize the other distros on other partitions.
I plan to have three 15GB root partitions, one swap, and one home partition for each distro.
Would I create a /boot for each distro? Or create one /boot with files from each distro copied there? Or should I do something else entirely?
I just don't want the distros to interfere with each other. Also, I don't want to use VMs for this, because I want to see what a real full-performance install is like for each distro.
The system came with Windows 7 installed.
After installing Ubuntu 11.04 (Natty) with Unity, I installed Xubuntu 11.04. All three OSes could be seen in the GRUB menu and I could boot any OS of choice.
Then I installed OpenSUSE 11.4. I suspect it installed legacy GRUB on the OpenSUSE root partition. Thereafter, I was not able to boot Ubuntu or Xubuntu.
I have now used a LiveCD (system rescue mode) to re-install GRUB on the MBR. However, I can only boot Win7 or Ubuntu. Can't access Xubuntu or OpenSUSE.
The results of my boot-info file are as reproduced below:

I created a customized Lucid image and installed on my computer which has 1 hard drive (/dev/sda)When I booted up .. it gave me an error indicating "Multiple active partitions" ... and did not boot up ...
I used my live CD and run as live session to check on the hard drive, When I issued the command fdisk -l on an terminal , the out put indicated that only /dev/sda1 is bootable, and other /dev/sda* were not bootable ...
I am not sure why I got the "Multiple active partitions" message at boot up time ..
Previously I'd installed Ubuntu Netbook Remix (Lucid) on my Acer Aspire One 751h netbook. the machine came with XP installed, so I installed Ubuntu as a dual-boot setup. I had various problems with the configuration of Ubuntu (nothing to do with the boot process, and now solved) so I reinstalled it.
What I'd actually done with the second installation was to install it again alongside both XP and the original Ubuntu installation (maybe that was also a stupid thing, but I didn't know it would work like that). When I realised what I'd done, I did the stupid thing, which was to delete the partitions with the older installation and swap file (using the Disk Utility).
After that, the next time I rebooted I went straight into grub-rescue. I don't know much about this, but I found a forum entry explaining the basics, so I can now issue grub-rescue commands that let me boot into Ubuntu. I've run update-grub and my /boot/grub/grub.cfg file looks fine.
However, I think this only kicks in once I've got past the initial boot menu and have chosen Ubuntu (now on sda5 - hd0,5). My problem is that the files/processes that load the boot menu on startup still have the old configuration, so when I reboot I still go into grub-rescue and I get 'partition not found' (or, since I recreated the partitions, 'file not found') and root is at (hd0,7).
Is there a way, once I've got into Ubuntu, of changing the information in the startup boot menu Alternatively, if I copy my entire file system from sda5 into sda7, would that do the trick?
