Debian :: "Not Optimum Mode - Recommended Mode 1280 X 1024 60Hz"
Apr 19, 2010
I am getting a pop up window saying: "Not optimum mode. Recommended mode 1280 x 1024 60Hz" In my case, this is happening after installing Debian 504 AMD64, the Samsung "SyncMaster 940N" that gives this message or warning was working fine for a few years on another machine under the previous Lenny distro.
The only way to get rid of this unwanted pop-up window (the monitor is working fine) is to press the "AUTO" switch on the monitor, there is no such option in the menu of the monitor to disable anything or change the resolution and it seems to me that, unlike what was suggested as an answer in similar threads, the problem is not with the monitor but with the distro unable to detect the monitor properly. The only mention in the "xorg.conf" file is as follows and running "dpkg reconfigure ..." has no other effect than creating a new exact duplicate of the file.
Section "Screen"
Identifier"Default Screen"
Monitor"Configured Monitor"

Greetings ubuntu members. I have recently been trying to install ubuntu 11.04 on my old computer and I installed ubuntu with no problems but everytime it takes me to grub, the monitor will turn black in 2-3 mins with a message saying Not Optimum mode 12080 x 1024. I suspect that this maybe a video card problem? I have a Radeon 9250 video card.

Below is a print out of my partition Table from Fdisk, in Cylinder mode, Sector mode, and then in expert mode?
Why in expert mode does it look like Partitions 2 and 3 share the same sector / hd / Cylinders? Is this OK?

I got myself a brand new pc, it has an asrock z68 pro3 motherboard and an i2500k proc. the screen is a dell u2311h the problem is i cannot get the resolution higher then 1280*1024. with 10.10 the monitor works perfectly, but the system crashes. so i want to use 10.04, which seems quite stable on my hardware.

I attempted to install Catalyst 10.11 for my ATI HD 2600XT and the system now only displays lines and a large block of pixels where the mouse would go. CTRL-ALT-F1 kills the system and does not provide a command prompt. This is a single installation, not dual-boot, but there is no Press Esc to access the Grub menu during startup so I cannot choose safe mode. I attempted to get into Recovery mode using the flash drive that I used to install the system and it tells me there is no Recovery kernel (I used the 64-bit Desktop installer, not alternative). Does anyone know an alternative to get into the Grub menu other than ESC during bootup? Alternatively, do I need to download the 64-bit Alternative ISO and create a new boot disk with it so I can access Recovery mode? Is there something else I'm not thinking of?

My linux workstation recently crashed. After rebooting, Linux (Red Hat 5.3) will not boot properly and automatically went into emergency mode or recovery mode i think. I can still see my /home/user/ and all the files inside.I boot from CD to rescue mode and tried mounting read-only the /dev/sd5 which contains the files in the crashed hard disk to try to copy out my files but mounting was unsuccessful (invalid argument). I checked the filesystem type using fsck -N /dev/sda5 and shows it to ext2. i tried to mount another known working hdd and was successful.
My question is why in emergency mode, the crashed hdd is able to be mounted automatically as read-only but cannot be done in rescue mode thru a bootable CD?Is there any special mount options used in emergency mode?I also cannot copy out in emergency mode booting from the crashed hard disk as everything is read only.

I ordered this USB 802.11n dongle for about $10 and am having problems.I found a firmware related bug (Bug #595455) that keeps it from working out of the box and got around that. I put the right firmware file in the right place and CAN CONNECT TO B or G Access Points.hen I put my AP in N-Only mode, I can see the network, but cannot associate. With the AP in mixed mode I can Associate using G.The most interesting thing I found was something that had very
few google hits (like 4). In the dmesg output after associating I see the message:
Successfully associated, ht not enabled(0, 1)The most interesting thing about this is the (0, 1) at the end.I don't know what that means but it seems like a clue as to what the problem is.This device uses the realtek chipset 8191S, there are conflicting reports on this, but all the reported possibilities seem to use the same driver from realtek (rtl8712_8188_8191_8192SU_usb_linux_v2.6.0006.2010 0625).Here is some random info:
Dmesg output:
[85082.620027] usb 1-3: new high speed USB device using ehci_hcd and address 6
[85082.754586] usb 1-3: configuration #1 chosen from 1 choice

I played with the graphics in kde4 and seem to have losy my installation. i have tried the rescue system option, recover system options and in desperation (i was just about to reinstall) tried booting in failsafe mode, and it worked!
where do i go to find out what the problem is regarding the normal boot mode? i think my pc is starting to resent the continual use of the reset button!

I installed ubuntu 9.10/9.04 on my usb key as live image couple of time. I have trouble when I try to install wine on my usb key. I am wondering what is the difference if I install my ubuntu into my usb key directly? will that be slower compared with live CD mode? I guess live CD mode may use memory as part of harddisk to save temepory files and normal usb linux installation won't do this for me. Is this true?
If so, do I have a choice to point my tmp directory to system memory area?

When I first installed ubuntu 10.10, the display was for some reason tinted green and shifted a few inches to the right. After experimenting with the resolution preferences, I eventually got it to a large resolution (1280x720 ... or something like that) yet is was quite blurry. I found out that the problem was with my monitor after I switched it to TV mode, then back to PC mode. It became perfectly clear! All I had to do then was adjust the screen positioning by shifting it left a bit.
Even though I have made the resolution I figured out to be default, whenever I turn the PC on after shutting down, it goes back to the "green-and-to-the-side" mode. :/ Ain't really a big problem, until I tried to fiddle with the resolution preferences s'more.
Somehow, I have set it to be twice as wide of the maximum my monitor can display, went back to being green tinted for some reason, and is completely shifted left (yet the right side is still visible) This means that I cannot see what is going on the left side, and cannot adjust the resolution preferences, nor can I click blindly cuz the border is only around my visible side of the screen. Now it is stuck like this.
I've researched many hours and eventually found the terminal command for the resolution preferences. it popped up on the visible side. Although it was to no avail cuz I HAVE TRIED EVERY SETTING AND OPTION and absolutely nothing changed. I assume a system restore would simply revert it back to the previous satisfactory settings, but the thing is I want to FIX it. I am new to this terminal stuff, so I want to learn it and all that. To put it simply, here's what I want:
Learn how to manually adjust resolution without depending on a simple dialog box. Make the satisfactory resolution default and consistent through turning it on and off. Link that could teach me the essential commands, all this googling is stressful. D:

I was reading about ext3 feature and I have read about its journaling modes. I would like to ask what is the default journaling mode of ext3 fs in slackware(or is it in all distro using ext3)? I'll install slackware when my new pc arrive and the fs I will use will be ext3 and I like it to have data=journal mode for its journaling. I have read in some wiki how to set the journaling mode into data=journal mode.
Code: # tune2fs -O has_journal -o journal_data /dev/sdXY Do i need to issue this command or is this the default mode in ext3 in slackware?

I have a brand new Z97-PRO (Wifi/USB3.1 version) that I got to replace a Gryphon Z87, and it was working great for the first day. I had my Debian and Windows drives both working, and I was working on getting GRUB reinstalled on the Debian drive in no time. At some point I needed to restore my Windows MBR for the millionth time, but this time was different. The Windows logo popped up and froze there. I know this is a thing that sometimes happens, but every other time since I replaced my Gryphon this process only lasted seconds. I let it sit for hours and it didn't move.
I then tried my Debian live USB, which loaded into the main menu, but upon selecting rescue mode it black screened and hung. This was an issue I experienced when I first got the board, but it seemed to work itself out after a few reboots and remained flawless until it just came back. At this point, I'm unable to get in to any of my OSes and I can't seem to successfully boot any external media in order to fix it. My BIOS is totally stock save for secure boot, which is set to Other OS, and memory in XMP mode. I also tried using an Ubuntu Live USB, but ended up hanging with the exact same Q-Codes as in Debian. I am running the system on 1 stick of RAM while testing.
Q-Codes at hang:
UEFI USB - AF (Exit Boot Services Event)
Regular USB - F6 (Reserved for future AMI progress codes)
Specs:
- 2 boot SSDs (OCZ for Windows, Kingston for Debian), 2 storage drives, and a DVD drive.
- The boot SSDs occupy SATA ports 1 & 2, the DVD drive takes up 3, and the storage drives take up 5 & 6
- i7 4770K, 32GB (8GBx4) Corsair Dominator RAM, GTX780Ti
- 750W Silverstone PSU

I decided to use Debian for my system at work, and while trying to set up the system this weekend I've run into a major problem trying to start X11. I'm not very experienced with Linux, so there is probably going to be some huge gaps in my knowledge as I've only used Ubuntu on my netbook with only a little terminal work, so bear with me. As background info I'm using a Radeon HD 4350 and an nForce 4 board with an Athlon XP 3200 ( I think). Yeah it's some ghetto hardware but it's good enough for what I need to do at work.
Anyway, I successfully install Debian using disc 1 here, and did the Advanced Installation. As a note, I installed Debian once using the standard install, but I was trying to run a few X commands that I only found out after reinstalling need to have X-server running, which it obviously isn't in single user mode. This shouldn't be an issue since I rewrote the partition table and am not using the drive for anything else. After the install finished and I restarted the computer, after the kernel loaded my screen shows wither "Not Support!" or "Input not supported." depending on which monitor I'm using. The first message comes from a cheap Japanese tv so the engrish is understandable, but from what I can tell it's the same error message for both. First guide I tried following was this one. I completed all the steps, and my xorg.conf is currently set at those values. For people who don't want to read through the whole thing:

When entering insert mode in a text file i want to edit while using rxvt-unicode, there is a p being inserted and a whole new line is entered as well. when i hit the insert key, vim enters insert mode but also types a p and forces whatever line i am on down a line. if num lock is not on, it will not enter insert mode by pressing the insert key but if i type using the keyboard and not the number pad, it still enters text. vim/mode keys work normally in xterm. is there some unusual configuration required in order to get vim to behave properly within rxvt-unicode?

I have a Debian 8 system here running off an SSD with a five-drive RAID5 array (md0). I can reboot this machine just fine until I do an apt-get update and upgrade, at which point it fails to boot. I get the following:
A start job is running for /media/Storage (the mount point for md0)
Afterwards it dumps me into emergency mode. journalctl shows me these worrisome lines:
Timed out waiting for device dev-md0.device.
Subject: Unit dev-md0.device has failed.
Now, I have a backup image of this installation from right before running apt-get update and upgrade. If I restore that image, Debian boots fine and mounts the array successfully every time. Until I update and upgrade again. I've seen it happen three times now.

After a large update of software I can nolonger open Squeeze. I get past the grub screen however before the gdm starts up the screen goes blank and stays that way. I have only one kernel showing on the grub screen.
I tried in Recovery Mode: Ctrl+Alt +F keys with effect and startx returns a blank screen, this is why I though to try loading another kernel to see if that helps. I'm using a Acer Laptop.
My question is: Is it possible while in Recovery Mode to load/install another kernel os that when I get back to the grub screen I have another kernel to try to boot into?
