OpenSUSE Install :: Restore System Search For Lost Partitions?

Dec 28, 2009

As I type this, I'm waiting (and waiting) (and waiting) for the Repair Tool Box, "Search For Lost Partitions" tool to stop running off of the install CD. I didn't actually mean to do that (I meant to select "repair file system!) and I don't see any way to abort it! How to I make it stop? (You can insert your best Deanna Troi voice there, if you like: "make it STOP!") Or do I just wait until sometime next week for this rascal to finish examining a THREE HUNDRED GIG partition, byte by byte . .. ?

Ubuntu Installation :: Installer Won't Recognize Partitions - Error Message Saying Partitions Over Sized

Mar 22, 2011

I used Ubuntu before, without problems but since the 10.04 version it won't recognize my partitions. I formated my laptop and partitioned it, installed Windows 7 64bit, which I need for my work, and wanted now to install Ubuntu 10.04/10. I then used GParted to check my Harddisk and it is having troubles to recognize my partitions, too while Windows finds them. GParted is giving me an error message saying my partitions are oversized. I am still in the beginning of my Linux experiences and so I don't know what to do. I have two 250GB harddisks (how Windows recognizes them),

Ubuntu Installation :: CD Doesn't Detect Partitions But No Apparent Overlapping Partitions?

Mar 3, 2010

Xubuntu 9.04 installation CD not detecting any of the current partitions. This all started when I reinstalled windows XP a few days ago.After, the computer wouldn't boot into GRUB and would boot directly into windows.Other threads have dealt with a similar issue, that of overlapping partitions causing libparted/parted/gparted to detect the whole drive as unallocated space. The problem in these threads seemed to be a corrupted partition table, in which the partitions overlapped with each other. So of course I checked the output of fdisk -l for overlapping partitions, but I don't see any obvious overlapping partitions. I've noticed that the partition that used to be linux swap isn't showing up in the partition table at all. I might just be missing something simple here and would like another set of eyes to help me figure this one out. Does the problem have anything to do with the partition table being out of order (ie. not in order of what regions they cover on the drive)? From the liveCD I've run

Code:

sudo fdisk -lu
sudo sfdisk -d
sudo parted /dev/sda print

and have received the following output:

Code:

ubuntu@ubuntu:/mnt$ sudo fdisk -lu
omitting empty partition (5)
Disk /dev/sda: 60.0 GB, 60011642880 bytes

Ubuntu Installation :: Order Of Partitions For Root / Home And Swap With Respect To Windows Partitions?

Feb 9, 2011

I am installing Ubuntu on the same hard drive as Windows 7. The partitions of Windows 7 have already occupied the left part of the hard drive. From left to right, the Windows partitions are one partition for Windows booting, one for Windows OS and software installation, and one for data which is planned to mount on Ubuntu. I was wondering how to arrange the order of partitions of root, home and swap, i.e. which is on the left just besides one Windows partition, which is in the middle and which is on the far right?

Ubuntu :: Having Poor Sound In The 9.10?

Jan 12, 2010

Ever since I upgraded to 9.10, I've had poor sound quality. There is occasional popping, hissing ans just generally poor sound. I've found several posts about loss of sound but no solution for bad sound quality. Didn't there used to be a way to select your sound in Ubuntu? I remember having a pull down choice of ALSA, Pulse or OSS. I can't find that any more and Pulse seems to be deemed the culprit in other posts I've read. How do I change to ALSA or OSS?

Hardware :: Change Primary Partitions To Logical Partitions AND Migrate Their Data?

Mar 28, 2010

I've installed Arch Linux onto my Western Digital SATA drive.I love it, best ever, however, I need the fglrx proprietry driver for better 3-d performace, and decided to create a new partition. I decided to install Linux Mint.Sadly, in all my noobishness, I forgot about the 4 primary partition limit (oops!) and as I have /, /home, swap, and /boot partitions (all primary) already installed, I have run into a bit of a problem.I resized my /home partition (almost 500GB) to about 225, and was then told I have over 200GB unusable space. Is it possible for me to change at least 1 of my primary partitions to logical partitions AND keep all the data intact (AND edit the arch configuration so that it'll still work) so I can install a second linux? I sincerely doubt it

Ubuntu :: 8.10 - IBM ThinkPad R32 Poor Performance

Feb 8, 2010

i'm trying to run ubuntu 8.10 intrepid ibex on an old hand-me-down laptop that i got from a family member, and i've noticed that the performance is actually much worse than it was on windows xp professional (32-bit).

first of all let me give you my specs:
ibm thinkpad r32
intel mobile pentium 4-m 2.0 ghz
ati radeon mobility m6 (i think this is actually the mobility radeon 7000 igp) with 16mb ram
256 mb ram (pc-2100)

i understand that these are very low performance specs, but it feels like the computer is running very sluggishly even for those specs. the computer ran just fine in windows xp, but is extremely sluggish in ubuntu. it seems like it detected all the hardware just fine, but i feel like it may not be utilizing the cpu and/or video to the extent that it should be. a couple of places where it really seems to struggle is when first opening new programs, viewing flash intensive web 2.0 type webpages (i.e. videos), and listening to music/podcasts (with rhythmbox).

it seems like rhythmbox really kills my performance more than anything else, but the performance is poor all around compared to xp, and i feel like that shouldn't be the case. like i said, i understand that the specs are poor, but it feels like it's not even living up to those specs. i know that 8.10 is old and outdated now, but it's what i had laying around and i figured that it might perform better on this old deprecated laptop than 9.10 would anyway. am i wrong in this assumption? would 9.10 perform better for me?

Ubuntu Networking :: Poor Connection On The Jaunty?

Jan 12, 2010

I'm trying to connect to the wireless netwrok of my university, which does NOT require any password. When the computer starts is automatically connects to the network and it always worked well, but now a message appears that says "authentication required" and it says that the network requires some sort of password or key. This is weird because it had never given me the problem. The options in the box are "Cancel" and "Connect", but "Connect" cannot be marked. There's also a dropdown box in the box that says "Security Type" and the option is "none". No other option is available for marking. After canceling the message and trying to connect like 50 times, I finally got a very poor connections. My email took forever to open and I opened the terminal to download something that someone said had solved the problem

Code:

sudo apt-get install linux backports-modules-jaunty

But it has taken forever to download, which proves the connection is working but it's in really bad shape. Any hints on how I may solve this? I read several bug reports and fixes similar to the problem, but they were very old (apparently a bug that was in Gutsy and then continued in some cases in Jaunty).

EDIT: Now I definitely can't connect. One strange thing was that at my house I couldn't connect either, but this time because I didn't even had the wireless option available anymore. I went to Hardware Drivers and realized 2 things:There were 2 drivers recognized, which is weird because I had always had only one, which is the Broadcom STA Wireless Driver, and there was another one, also wireless related,. but which name I don't remember Both drivers were deactivated, which again is strange because the STA was always activated before.

I activated the STA driver only. because I feared that two activated wireless drivers may have conflicted with each other. The Wireless started working again and I connected to internet with no problem. My home connection, by the way, needs a password.Now, back in University, whose wireless does not need password, the same problem happens. It says "Authentication required by wireless network" "Passwords or encryption keys are required to access the wireless network 'UC'." The a dropdown box with the title "Wireless Security" and with the only option available marked: "None". The the options in the dialogue boz are Cancel and Connect, which cannot be chosen.

Ubuntu Multimedia :: Very Poor Refresh Rate

Jun 5, 2011

I just built a home media server. It's using a Gigabyte E350N-USB3 motherboard with the AMD Fusion processor. So far, everything seems to be working fair enough. However, when it comes to video playback via an HDMI cable to my TV, it's unwatchable. It is okay during slow scenes, but any sudden movement or high action scenes and the problem becomes obvious.I don't know how to explain it other than it appears to have a problem refreshing quickly enough. I see horizontal lines across the film. I originally thought it might be due to low quality AVI files, but I just tried a DVD and it did it just the same.

I'm pretty knew to Ubuntu, so I'm not sure if there are some settings I can tweak, or if I am missing some drivers. Any ideas on where to start?

Ubuntu :: Poor Performance On Pentium 4 Machine?

Aug 4, 2011

I just installed Ubuntu 10.04 on a laptop that was given to me. It is having a lot of lag issues,especially when playing videos and visiting websites using flash. It's an Intel Pentium 4 2.4GHz machine. I think that it should perform better because I had used and AMD Sempron 2.0GHz machine with Ubuntu before and video playback was much better than this. I'm thinking that my problem is the graphics card driver. Here is the card that this machine has:

Code:
:~$ lspci | grep Radeon
01:05.0 VGA compatible controller: ATI Technologies Inc Radeon IGP 330M/340M/350M
The AMD machine was using a VIA graphics chipset.

I used the command "Xorg -configure" to create a xorg.conf file, hoping that might help. But it didn't. Here it is:

Code:
Section "ServerLayout"
Identifier "X.org Configured"
Screen 0 "Screen0" 0 0
InputDevice "Mouse0" "CorePointer"
InputDevice "Keyboard0" "CoreKeyboard"
EndSection

[Code]...

Is there any tweaking that I can do in the xorg.conf that might help? I don't know which of those options I should set. I also tried changing the driver to "ati" but that did nothing. found some info for settings with "man radeon", I'm going to try some of those out.

Ubuntu Multimedia :: MythTV - Poor Flash / No Gnome

Mar 28, 2010

I am working on a Mythtv frontend/backend/desktop and am at a loss. The goal is to use myth to record programming from the free broadcasts (i fired the cable) and the desktop to watch flash video of the shows that aren't on the broadcast networks...like TNT, natgeo or the comedy channel. Software is Mythbuntu 9.04 running nvidia 180 drivers

I imagine the hardware is adequate, it is well above minimum specs that I can find.
AMD Athlon 3000+ processor
2gigs of PC2700 memory
Gforce 6200LE 512MB DDR2 video card AGP
Hauppage HVR-1600 tv card PCI

I have two problems, well three now if you count the crashing firefox. Myth TV is working fine. There was a conflict with the video card and the tv card. But now when I try to view flash video it is jittery...Firefox has started crashing now and that is a new thing. It will allow me to start a video and the the window will just close with no warning. I tried a local radio stations website and it did the same thing. When I connected to pandora it worked but I could only get the songs to play for around 30 seconds before it would skip to the next one.

I wanted to have the Gnome desktop instead of XFCE but nothing I do seems to change it. With that explanation in mind:
Is this hardware enough for what I want to do?
Is loading Mythtv first then adding gnome the best solution? (if not, I think I can redo the Mythtv setup and conflict resolution again without cracking up).

Ubuntu :: Poor Desktop Performance With NVidia And Four Monitors?

Dec 20, 2010

I experience very poor desktop performance on my system. General clicking responsiveness is poor, taking over second or two to focus to a new window, move windows around, ... etc. The Xorg process constantly uses over 60% of the CPU even when I'm doing nothing, and when I do click around it will quickly go up near 100% usage. Performance is initially OK when I first launch into my Gnome environment, but it soon deteriorates within 30 minutes or so. Eventually, after days of being up and running, my desktop will crash.I am running Ubuntu 10.10 with latest upgrades. I have four monitors attached to my "nVidia Corporation G98 [Quadro NVS 420]" graphics card. I am running the "NVIDIA accelerated graphics driver (version current)" recommended in the Ubuntu "Additional Drivers" app. I get a fair number (hundreds) of these in my /var/log/Xorg.0.log:

Code:

[862923.098] (WW) NVIDIA(2): WAIT (1, 6, 0x8000, 0x0000ba04, 0x0000ba14)
[862923.099] (WW) NVIDIA(3): WAIT (1, 6, 0x8000, 0x0000ac44, 0x0000ac54)
[862923.099] (WW) NVIDIA(0): WAIT (1, 6, 0x8000, 0x0000fca0, 0x0000fcb0)

[code]....

though they don't appear constantly while my desktop is running (I assume they may come in batches?). Not sure if they're relevant. A separate issue, though possibly related, is the SpeedCrunch app (a desktop calculator) is guaranteed to crash my desktop as soon as it gets focus. Here's the relevant output of "lspci -v" which shows my graphics card:

Code:

03:00.0 PCI bridge: nVidia Corporation NF200 PCIe 2.0 switch for Quadro Plex S4 / Tesla S870 / Tesla S1070 / Tesla S2050 (rev a3) (prog-if 00 [Normal decode])

Ubuntu Installation :: New Install, Poor Display And No Wireless?

Apr 9, 2011

I'm almost a complete noob when it comes to Linux. All my computers 'til now have been Windows boxes (3.1 on up to XP). I do know a little, I've tried to switch to Linux since RedHat 7.2 but never got this far (I can connect to the Internet!). I currently have two issues I really need to get past this weekend, or I'll be forced to spend $110 on Windows 7 - which I REALLY don't want to do. I can't get the display right, and I can't get the wireless working.

My computer is an AMD Zacate on an ASUS motherboard with integrated graphics (ATI Raedon 6380, if I remember correctly from this afternoon). I'm using an Insignia 1080p TV as my sole monitor. The wireless card is a Zonet ZEW1642S which uses the Ralink RT3062 chipset. Today I finally got the monitor to display in 1920x1080. I updated the ATI drivers (HDMI sound started working after I installed them) and downloaded Catalyst. I've been trying to get through the xrandr instructions to get the screen to fit, as I can't see the top and bottom bars. Also, I think it's displaying in 1080i instead of 1080p. Text quality is atrocious compared to the 1024x768 resolution it had earlier. The screen refresh is terrible.

I opened terminal, inputted "xrandr" and got:

Code:
Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 1920 x 1920
DFP1 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 698mm x 392mm
1920x1080 30.0*+ 30.0
1776x1000 30.0
1680x1050 30.0 30.0

Ubuntu :: Poor Transfer Speed With Samba And Http

Apr 22, 2011

(this is a repost of the same thread in the networking/wireless forum, I think it's better suited here but couldn't see a way to move it) I have a Proliant Microserver, I have Ubuntu Server 10.10 installed onto to a USB stick (the server has an internal USB port). The storage drives are Samsung SpinPoint F1s. The server is plugged into a gbE switch, there is a link from that to a 200mbps powerline link, from there it goes to a 100mbps switch and then to my machine I was testing from.

I realise that a powerline link can often slow things up, but I use the same link for my Internet connection which will happily pull files down at around 4.3mb/s.. so I know the link isn't the bottleneck. If i copy anything via any of the samba shares then it transfers at around 1.5mb/s. This speed does not change if I try plugging the client into the same gbE switch as the server. Similar spees are shown if i transfer it over http via apache2 as well. Client machines are laptop running ubuntu and a win7 desktop. Speeds are the same copying to both of them. I have applied tweaks to samba as described here;

Ubuntu :: Nvidia Quadro NVS 135M - Poor Video?

Jan 24, 2011

Like the title says, I have the Quadro NVS 135M in my Dell D630. It's working (well, besides the startup screen issue - Plymoth... not a fan!), but when I watch a movie the image ?flickers? annoyingly. This is something I have never experienced before, with allegedly ?inferior? video cards. It's odd though, isn't it - better video card, inferior output!?!
