Ubuntu Installation :: 11.04 LiveCD - EDID Checksum Invalid
Jul 17, 2011
I burned a new disk with ubuntu 11.04 image and I managed to boot the live cd using my external monitor, I've installed and went into my monitor settings, it displays my external monitor as unknown and doesn't even detect my laptop screen. Changing the driver being used in my xorg.conf to vesa allows me to boot properly and ubuntu uses my laptop screen (yet it still detects it as an unknown monitor). Installing any nvidia driver and using it breaks my system. Heres an image of the laptop when using the nvidia driver (btw I can still hear the ubuntu sound that plays when its reached the logon prompt).

I just installed jessie on a machine that had been running wheezy with no problems. Now I see that a kworker process is hogging nearly 100% of one of the CPUs. I am not sure how to proceed with solving the problem even after doing a number of Google searches.
I'm not sure if this is related, but I am getting the following when I run 'dmesg':

I have got a very frustrating problem. I am not new to Ubuntu but this time I bit my tongue! Actually it is a problem related to my graphics card "Intel 945GM" , it is a real crap card but it is working fine with Windows XP pro (I use windows just for testing)!
Problem : My monitor DELL ST2310 would not work under DVI mode (only VGA mode is working fine)! I tested with Kubuntu, Ubuntu (several distos), Fedora 13.. Upon booting, I get this error message :
Code:
EDID checksum is invalid
remainder 130
the monitor DVI connection is working perfectly under Windows XP. This means the Intel 945GM cannot read the EDID hexadecimal data transmitted by the monitor through the DVI connection. Yet, System recognizes the graphic card's DVI-D port but set it as disconnected.

I am trying to install Unbuntu 11.04 on a Via raid 0. I have windows already setup and it boots fine, but Ubuntu does not see the raid set. Running dmraid -ay (or any valid switch with dmraid) returns :
sudo dmraid -ay -v
ERROR: via: invalid checksum on /dev/sdb
ERROR: via: invalid checksum on /dev/sda
no raid disks
mainboard is Asus M2V, with 2x Hitachi 250Gb disks in raid 0 configuration set in BIOS. I have a 3rd hard disk on the onboard Marvell 88SE6121 sata controller but this is not seen at all by Ubuntu either. I was thinking of installing it here if Ubuntu does not work the RAID, but no go it would seem. I do remember installing an earlier version of ubuntu on this very same board using RAID 0 (2x 80Gb drives at that time) and the RAID was reconised and worked fine straight from live cd to full install.

Lots of these in my dmesg, dont like that. Don't think it should be there. Don't know how to get rid of it. What i do know is:
It's intel graphic card related on Ubuntu 9.10 2.6.31-20-generic #57-Ubuntu SMP Mon Feb 8 09:05:19 UTC 2010 i686 GNU/Linux On a EEEPC 1000H

I have installed a fresh copy of FC14 and when I logged in locally for the first time I was getting the error messages below. Now these same messages are filling up my messages log and it's running non stop in the background. Has anyone seen anything on this error? I have searched through Google looking for help and I'm not finding much.
This box is a simple file/web server with no monitor hooked up and no GUI. I have also included the lspci ouput below if that might help. Really looking for any suggestions or input on how I might stop the error reporting since is filling up my log files quickly.

I'm running 2.6.32-28-generic. I have a raid1 (two 1tb drives with two partitions... one for / and one for /home.) After a power outage, I'm seeing grub complaining about /dev/md0 not existing (ALERT! /dev/md0 does not exist. Dropping to a shell!)
I booted to the latest live CD to have a look around. My dmesg output includes these ominous lines:

I finished downloading of "openSUSE-11.1-KDE4-LiveCD-i686.iso" file. I downloaded it by Opera WB. Then using Nero I burned this file to CD. But there is a problem with boot. Please, make a support to this problem. Maybe file, which is in a site opensuse.org is damaged?
After the reboot of computer this text appears:

Using a 10.04 LTS installation disc, fresh are my install Firefox, multiple software, and the software updater thing did not work. Figured maybe I messed something up. I installed 10.04 LTS about 6 times from scratch, no other OS on the system. They all had issues loading software, I click on whatever it goes to launch and nothing ever comes up. I started doing updates through the command prompt using
sudo apt-get update
sudo apt-get upgrade
Then multiple packages broke. Tried sudo apt-get -f install but I keep getting an error that openoffice and firefox fail their checksum. Click on upgrade by 10.10 version gives me the screen that says are you sure, with all the information for the distro and then brings up a window that says download 2 out of 2 and it also crashes. So I figured alright, maybe the CD version I have is messed up. I downloaded the 10.10 iso image and burned it three times. Two of my live cds take me boot me to the purple ubuntu starting screen but nothing is displayed except for a little icon with a keyboard and the disabled person at the bottom. Then my computer reboots it does that continuously.

The CheckSum file I downloaded for Fedora 12 contains a header line indicating the checksums are SHA1 when in fact they are SHA256.

is there anyone who checked your downloaded file against the provided key? i have successfully downloaded the Fedora-12-i386-DVD.iso several times, but the SHA1 is not the one in Fedora-12-i386-CHECKSUM is there anyone who has the same problem? the SHA1 i calculated is: 0dc8ed436f0b44874454a379e8de5ad057c0115d

I just downloaded the "Fedora-11-i686-Live-KDE.iso" and "Fedora-11-i686-Live.iso". I want to check if the downloaded files correct or not. I can use a tool to get the md5 sum of the downloaded files. But I want to compare them with the original ones.

I've downloaded the
Fedora-12-x86_64-disc1.iso
Fedora-12-x86_64-disc2.iso
Fedora-12-x86_64-disc3.iso
Fedora-12-x86_64-disc4.iso
Fedora-12-x86_64-disc5.iso
files. I then downloaded "Fedora-12-x86_64-CHECKSUM" and ran sha1sum.exe on my iso files and compared the results. They were wrong for all 5 iso files. Figuring there was a problem with the way I was trying to evaluate the checksum I burned a CD with the disc1.iso. I received a "INSERT A BOOT DISK" error from my machine. I then tried downloading the disc1.iso again and ran checksum on my newly downloaded file and get the same checksum on both the old and new disc1.iso files.
When I run:
I get the response:
It seems to me the checksum value should be:
What am I doing wrong? I've installed many different distros in the past and am pretty sure I burned the iso file not just copied it to the CD.

I'm trying to upgrade to F11, and I'm having trouble. I attempted to download the x86_64 DVD .iso image by bit torrent, and it seemed okay, but when I started the installation the DVD failed the initial integrity check. I tried a second time with another DVD and got the same result.I tried running md5sum on the .iso image, but the response did not match what was in the CHECKSUM file that came with the .iso image -- should it? I tried downloading a live DVD image for comparison and found the same result - the response to the md5sum command did not match what was listed in the CHECKSUM file.Should these checksums match, or am I comparing apples and oranges? I thought the bit torrent client was supposed to check the files, but I'm not sure about that.

Suse asks me to install it anyway but then decides to not let me install it, only leaves skip, cancel and retry. when doing skip, suse also managed to fcuk up Grub and removes all the entries for suse. Installing the driver doing like ATI Proprietary Driver Install Guide | openSuSE 11.2 vanilla - openSUSE Forums
fails miserably too. the free radeon driver on my FirePro V7750 on the Dell 6400 still has artefact all over screen, I hardly can type., this linux installing is still quite frustrating. or should I try Linux maybe in a year again?

Bottom Line: Dvd Drive died in my toshiba laptop and it was replaced (not before tech for some reason reformatted the Win7 partition... which was 100% un-needed, but thats beside the point now. I redid win7 (the tech installed vista) and am TRYING to "redo grub". Facts: The Slackware AND Ubuntu Partitions ARE STILL THERE and when i use SuperGrub Boot CD (which doesn't restore my grub by itself) to boot into slackware, i can see ALL THE CONTENT of both Linuxes still there including grub on ubuntu partition
(Tri-Boot: Ubuntu, Slackware, and WIn7) I had it working for two years or so, SO i know this "setup" works fine. I am A) Trying to do this as simply as possible. B) Trying to avoid the need to download a 800MB ISO (as seen for this issue on this forum) and trying not to have to reformat Ubuntu Partition (though I have the .Debs I have downloaded for it backed up ... all 1.7GB of them) I have /dev/sda1 as win7, /dev/sda2 as Slack and /dev/sda3 as Ubuntu (which contains Grub Legacy).. Every command I do seems to result in an error like "invalid command" or "invalid Execution format " (i think that second one is right) type errors. I compiled (awhile back) a few kernels for Slackware, but feel goofy that I cant figure what i this out (what i thought was going to be a "2 minute" fix)

I'm not sure what has happened. The last update I did was on the 15th. I've rebooted a number of times since then and haven't updated/installed any packages. But clearly I must have changed something but for the life of me I can't remember changing any settings video related. Now X does not start. This is what I get now

I am running Wheezy 7.9, I have a Biostar motherboard with integrated Intel graphics (945 chip set), and a Viewsonic va912b 19" LCD monitor. I have recently been having problems with the computer not being able to read the EDID data from my monitor. About half the time the EDID is read okay. So, in order to set the monitor to the desired resolution I have created a shell script to set the resolution after I log in. Knowing that my monitor supports 1152x864 @75hz I used cvt to get the modeline info.
Code:
Select allroot@JohnBoy:/home/john# cvt 1152 864 75
# 1152x864 74.82 Hz (CVT 1.00M3) hsync: 67.71 kHz; pclk: 104.00 MHz
Modeline "1152x864_75.00" 104.00 1152 1224 1344 1536 864 867 871 905 -hsync +vsync
Then I wrote this shell script.
Code: Select all#! /bin/sh
#! /etc/init.d/monitor_1152x864x75
#
#add monitor resolution not being found at startup
#data from cvt
xrandr --newmode 1152x864_75.00 104.00 1152 1224 1344 1536 864 867 871 905 -hsync +vsync
xrandr --addmode VGA1 1152x864_75.00
exit 0
It works fine, but I see a difference between what cvt gives versus what I see in the xorg log file (when I get a good EDID read). Here is what I see in the xorg log.
Code: Select all[ 17.611] (II) intel(0): Modeline "1152x864"x75.0 108.00 1152 1216 1344 1600 864 865 868 900 +hsync +vsync (67.5 kHz e)
Notice that there are some small differences in the horizontal and vertical timings, cvt versus xorg log.
The biggest difference, to me, is that cvt has -hsync and the xorg log shows +hsync. I would assume that the data shown in the xorg log file is based on what was received from the EDID and therefore is what the monitor expects. Is that a correct assumption? And might using -hsync as per the cvt, versus +hsync, affect the monitor operation? Using -hsync does not appear to create any kind of video artifacts (tearing or distortions).

A few months ago my monitor broke and began using an old one that does not have EDID.Since then i havent been able to configure my computer with a stable video configuration.I`ve tried a thousand times to edit xorg.conf and i actually got it let me use resolutions higher then 800x600, but when i reboot my computer my usuall setting 1024x768 gets switched back to a lower one - its a pain... my icons get scrambled, the gnome panels, etc.Do I need to edit any other file then xorg.conf?
And another thing I noticed today is that the gnome display manager does not recognise the higher resolution of nvidia-settings. Does it have a seperate settings file?

Apparently you can't get EDID information through a Displayport->DVI adapter. That means that a default install of Lucid (or Natty!) does not recognize the resolutions of any monitor connected with such an adapter.
I'd rather not create an entire multihead xorg.conf just to specify NoDDC. Is there any other way to pass that option to X?

Trying simply to insert into table. Have succeeded in doing this but now want to correct user use of invalid characters. If I'm understanding correctly, Real-escape-string seems to correct these, so I've been trying to figure out how to use it. A short, test code version gives me a syntax error at INSERT VALUES, which--because it still has the single quotes in the text--tells me the real-escape-string didn't work. The code below gives me a parseing error with invalid $END at </body>.
Insert Error: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ' VALUES (UTC_TIMESTAMP,'What's happen' bra?')' at line 1 Parse error: syntax error, unexpected $end in /home/powere15/public_html/DB/exercises_insert_record.php on line 94

A friend of mine has asked me to install Ubuntu for a long time. Today I set up his partitions with Lucid LiveCD and GParted.
However, the LiveCd throws an error that makes me hesitant to continue.
If I boot a LiveCD on my computer I get a question meaning "run Live or install?"
This question does not appear on my friends computer. The first thing you see (about 2 min after boot) is an alertpanel saying something like "The installer encountered an unrecoverable error. We will now set up a desktop environment so you can investigate the problem." After that the normal Lucid (Live) desktop appears and functions well, as far as I can understand.
Sorry for not being able to give more data about my friends system. It is a stationary computer about 2 yrs old, running XP. I can't really make investigations on his system either. I had hoped to go there next time and just install Lucid.
Maybe one should try the alternate installer, but my friend just got used to the LiveCD and I would therefore like to use the LiveCD.
I don't understand why it seems to start installation by itself.
Most of all. I wonder if it is a good idea to run the installation from the desktop icon? Maybe it will encounter the same error that the LiveCd seems to encounter at startup?

How do I get advanced installation options on the LiveCD? In former versions, I could hit F4 for modes. Do I need to use the alternate CD instead?
For reference, this is what I'm trying to do.

I had problems with the system not reading the monitor EDID and have fixed the problem by adding an override file in xorg.conf.d and all of that seems to be working well (although the system has not failed to read the EDID since I implemented the override. go figure).
The thing that I am wondering about is something I see in the Xorg log file. At the end of the log file, after everything seems to be configured, there are six (6) identical blocks of information regarding the EDID and modeline settings. Is this normal or is X stuck in some kind of loop? Everything is working and I am not waiting an inordinate amount of time to log on, or after. Just curious. Here is the log file.

However when I put them in my current computer and restart, the computer simply ignores them and carries on with vista. I have been testing out the live CD's on VirtualBox and on my second computer and they look pretty nifty But the computer just ignores them as if they weren't there.
