Sometimes the screen displays four miniature versions of itself. Sometimes there is no display of the pre-boot message. When normal boots occur, often the screen display disappears entirely and irrevocably after about ten or twenty minutes.Sometimes everything behaves well with no troubles.
View 11 RepliesI'm not sure what to call the semi-transparent sidebar with a random collection of unconfigurable icons, but I don't think it's working properly.
1. When I move my mouse to the left edge of the screen, it doesn't always appear. Sometimes I have to move my mouse back and forth, back and forth, several times.
2. What it's doing right now is even worse... it appears, but as soon as I move the mouse a *little* bit to the right to actually click an icon, it disappears.
What is causing this? Surely it's a bug? How do I make the sidebar the absolute top priority for the screen edge so that it always catches it and appears? how do I configure it? I can't right-click on the sidebar itself. I can right-click and remove some icons. Other icons, like the grayed-out (but still active) "recent files" thing cannot be removed.
I received the Ubuntu CD by mail the other day and tried to install a dual boot with it. I first tried it out by running from the CD and the first problem I had was the screen froze after the splash screen. So I lurked around for a bit and found out that I can press any key on the screen with the keyboard and person to get to a different screen. At this screen I entered "F6" and then entered "nomodeset", this allowed me to pass the splash screen.
Next, I got into Unbuntu but I found out that the keyboard and mouse weren't working, so I lurked again and found out that I have to enter "noacpi" (sorry if I got that wrong, I forgot the name ). I ran by CD once more and everything worked, so I decided to finally install it next to my Vista. However, after installing it goes straight to the splash screen, and the freezing happens again. The screen where the keyboard and the person are not showing up so I have no idea how add the "nomodeset" and "noacpi". So my question is, how do I get to the screen where I can add both those things? Also, is there a way to add it permanently so I don't have to keep pressing F6?
I have a problem booting anything from USB stick on my IBM Thinkpad T42. It used to run normally, I could even install Windows or Linux from it, but now it stopped working. This particular concern is about booting freshly installed Xubuntu version 9.04 off a Kingston 4GB flash stick. I've installed Xubuntu using usb-create program directly from a booted live cd. Installation went fine and all the options in BIOS are setup correctly (I think). In boot menu in BIOS the stick is recognized correctly and + appears in front of it. Stick is selected as primary boot device. BIOS usb support is also enabled.
Now when I power on the computer, it reads something from the stick and stops right after displaying:
SYSLINUX 3.63 Debian-2008=07=15 EBIOS ... etc...
Then nothing happens and the text stays on like this.
I recently got the Message, that i should do a partial System Upgrade. It included an update to Kernel 2.6.34. Since this update, i cannot boot with this kernel:

i can still boot with older kernels, but many drivers including wifi and graphics drivers dont work there anymore.
I followed the following two articles to create a bootable USB key that will run the Kaspersky Rescue Disk, but both methods fail, using two different USB keys:
UNetbootin - Create Bootable Live USB Disks For A Variety Of Linux Distributions From Windows Or Linux : "Determining root device: Could not find the root block device in ."
Creating Bootable Kaspersky Rescue USB Disk : "Could not find kernel image linux"
Kaspersky only provides support for when trying to boot from a CD. Does someone know what I could try to get this to work as shown in the articles?

Put together a PC using the following:

Plus an old case and PSU and an old 18gb IDE drive, and an old CD-RW drive
I put the CD in and boot the machine. The initial Ubuntu screen comes up ("Ubuntu" with the line of dots below it) for a few seconds, and then it disappears and I see this text:
(initramfs) mount: mounting /dev/loop0 on //filesystem.squashfs failed: Input/output error
Can not mount /dev/loop0 (/cdrom/casper/filesystem.squashfs) on //filesystem.squashfs
At that point it hangs and will proceed no further. I've tried this with the latest Mythbuntu Live CD and the latest Ubuntu Desktop Edition Live CD. Both were x64 versions.
I downloaded Fedora-14-i686-Live-Desktop.iso and used the Fedora liveusb-creator to put this on a 2GB USB stick. Everything seemed to have gone well and it said complete; however, when I try to boot from the USB stick, I get a black screen with a linux copyright notice at the top and it just stays at that screen forever. I tried this on two computers with the same results.
I'd previously tried with Ubuntu and had a similar issue, it would go to a purple (if I remember correctly) Ubuntu screen and it sat that forever.
i am fairly new to Ubuntu. i was using it fine for a month, but today, when i booted my computer up, it came up with a black screen instead of the normal purple ubuntu screen. the black screen had white text on it, and asked for my username and password. from there, it was a terminal prompt. i have been google searching for a while, and have tried typing "startx", "sudo apt-get install ubuntu-desktop", "sudo gdm", and i have also tryed uninstalling xorg, and reinstalling, and none of these things wanted to do anything for me.
View 4 Replies View RelatedI switched a working Lucid KVM guest from linux-server to linux-virtual and it could not mount root at boot time and issued a panic instead. Switching back (booted from CD and used "rescue a broken system") revived the VM.
My first guess is that some DM driver module needed for LVM is missing from the linux-virtual package.
I've just migrated to Debian from Ubuntu on my server. So my first post here. I've had some problems and questions when installing and configuring Debian, now everything seems very smooth, but still I can't find answer to one question. My machine is headless and I allways use SSH to it. I have several partitions on machine so if one of them fails on booting time with fsck, I need to press CTRL+D combination to continue. In that case I need to go to the machine with monitor and keyboard and press that combination. Is there any way to automatically continue for example after 30 seconds ? Then I could log in to the system and check log files what is wrong. How can I do that ?

However, after install and reaching a CLI (on the HDD), when I run startx, my monitor simply displays 'invalid format' (obviously this works fine via the LiveCD)... I've installed Ubuntu and Fedora a few times on a few machines, and have never had any issues with the display... not sure where to start troubleshooting.
View 4 Replies View RelatedDoes anyone else experience this phenomena? It only happens on one of my PC's, my Compaq Presario M2000 laptop.The icons for various applications in the top panel load eratically on boot up. E.G sometimes the wireless icon doesen't appear , sometimes it loads twice. Sometimes the Sound Preferences (the speaker icon) is missing, Evolution Mail etc etc. Even the shutdown icon occasionally is gone. It sees limited to the ones on the right side and doesn't seem to affect ones such as Firefox that I've dragged up there myself. It doesen't happen every time, I'd say about 20% of boot ups this happens.
View 9 Replies View RelatedI'm migrating my OpenSuse 11.3 (which was update from 11.2, 11.1 ........ ) to a new hard drive. My partitions were reiserfs and in the migration I'm "converting" them to ext4, the conversion process is simple and it works fine for all of them except the root one:
1) I create a new partition on the new hard disk (bigger than the original one)
2) I format it with ext4
3) I copy all the data with cp -a from the original partition to the new one
I already have all the partitions migrated to the second disk, then I have tried to do it with the root partition:
-I've booted with a system rescue CD and I've done !9 2) and 3) with no problems.
-I've edited and changed al entries in fstab and grub conf (menu.lst) to point the new partitions
-I've reinstalled grub and it seemed It will be no problems booting, but
It begins booting, the grub menu appears, It begins booting the kernel, but suddenly:
waiting for /dev/root to appear: OK
fsck.reiserfs -a /dev/sda2
........
mount -o ro,ad,user_xattr -t reiserfs /dev/root /root
and it fails, because sda2 is not reiserfs, but why does it try to mount it as reiserfs if I'm not saying anywhere it is reiserfs?
This is my fstab:
Code:
#/dev/disk/by-id/ata-ST3160211AS_6PT0V05Y-part2 / reiserfs acl,user_xattr 1 1
/dev/disk/by-id/ata-WDC_WD5000AADS-00S9B0_WD-WCAV91599607-part2 / ext4 acl,user_xattr 1 1

I've booted it also with SuperGrub2 disk and the same thing happened, so I think it's not a grub problem but I don't wknow why it tried to mount the root partition as reiserfs.
I just upgraded from 8.04 to the lucid beta (yes I was slow to move on that), and chromium's scrolling is HORRID! It jumps and skips both when I use the mouse wheel or when I drag the scroll bar.
Any ideas? Firefox scrolls just fine. It makes using chromium very unpleasant because any time I have to scroll I feel like I'm back in 1992.
I did some searching and found lots of complaints, so I thought I was close to an answer until I looked at the date, it was late 2008/early 2009 when this was an issue.
I've been having some problems copying files to USBs. If I'm copying a large (100MB+) amount of data, at random points the transfer will just stop for 30+ seconds before continuing. Sometimes it doesn't start up again at all. Consequently, the write speed drops to less than 1MB/sec, sometimes as low as 100 KB/sec. I do not have these problems on Windows 7, where I achieve speeds of ~16 MB/sec easily. I have had the same results with several USBs (2-32 GB) on several file systems (fat32, ext2) with several different computers running fully patched versions of Ubuntu 10.04, which suggests the problem is related to the way the OS accesses the hardware.
View 6 Replies View RelatedI built a RAID5 storage array using 'mdadm' on 3x WD Green 1TB hard drives. I used the Disk Utility GUI to create the array and it took about 24 hours to build. When I started copying files to it I noticed it performed at decent speeds for a while, then got really slow, the sped back up. Just for laughs I ran the Read-Only Benchmark function in the Disk Utility and got a graph that would even confuse stock brokers.Any thought on what the issue might be? I tried searching around for an answer, but most people are only affected by wirte performance issues not reading.

I don't have anything connected to the HDMI connection on the ATI video card, and only inputs on the M Audio Delta 44 card.
wired is fine and fast. Wireless connects but connection goes from 100% to 53% at random, making the connection pretty pointless to use.Probably get fixed in an update. I have tried uninstalling network manager and using wicd. No luck. Well, luck, as in I could connect, but exactly the same as Network Manager.The card is a Realtek RTL8191SEvB.

I also disconnect my optical wireless USB mouse, and still have the same erratic cursor problem. I do not have the ANY problems with Win 7 -64 bits. This is a serious problem. It will render any laptop useless with Linux I so look forward to using Linux.
I am having a problem with how my windows behave.My windows will maximize and minimize over and over, scroll bars will scroll to the bottom/right automatically, if I click a menu it will pop up for a fraction of a second and then go away. It makes my desktop almost unusable.I can't figure out if this is a mouse or video issue. I have a radeon 9500, and a logitech LX3 optical mouse. BTW, this problem is present in other distributions on my system. I am running KDE. It even does this on the livecd.
View 1 Replies View RelatedUpgraded via Update Manager from 9.10 sound-previously-working-just-fine-system. Now, for example, running any audio-producing app (Rythmbox is a good example but its the same for anything including out of a VirtualBox XP install or with MythBuntu): The main volume control functions, but goes from muted to full volume in just 4 steps; raising it higher has no effect. It gets stranger: in Alsamixer or gnome-alsa-mixer I can see that lowering the desktop volume control to mute causes Master, PCM, Front, Surround, Center, LFE, and Side all to go to zero. Raising the desktop control one step causes all of these but Front to go to 100% instantly. Increasing the desktop control by a few more steps causes Front to step to 100%, after which no further volume increase is perceived. It's as if each step in the desktop volume equals some 25% of the Front setting, and 100% of the others. The audio setting in System, Preferences, Sound, Hardware is "Analog Stereo Output."
If I click 'Mute' on Master in the mixer then all the speakers mute, but unmuting Master does not unmute anything else. Only after I move and release the mouse-down state from the master volume do the other channels unmute. The volume control in Rythmbox, on the other hand, works seemingly correctly (maybe its going thru Pulseaudio?) And as an aside, why are there no controls for Pulse if it sits on top of ALSA?
I'm really confused by this, as all of it work as "expected" while running 9.10. Here is some output from this system (an ASUS M4A78T-E):
