Ubuntu :: Ctrl-alt-F1 - F6 Blank Screen On Maverick?
Nov 29, 2010
I recently installed Maverick 64-bit on a new HP 8740w (NVidia Quadro FX 2800M video). When I try to open a console using CTRL-ALT-F1, I get a blank screen (no cursor). The console is running (I can log-in blind), but no video. I have tried several solutions (modifying the GRUB video mode, and the solution in this thread. Nothing changed. I am using NVidia driver v173. WHen I revert to "current" I get a console login, but gdm won't start.
Any suggestions to get both gdm and console at the same time? I'm trying to configure the system so I can use multi-monitor in a docking station, so I'd like to know I can get to a visible console before I try that. I should mention that I was able to see the console just after installing 10.10, but in the days since, something (update?) changed to cause it to go blank. I had to make a few changes to get ACPI to behave on this system. I'm not sure when the console went dark.

When I press Ctrl-Alt-F1-F6 the tty is a blank screen. I can type but it doesn't ask for a login or anything.

I cannot access xterm or an tty using ctrl alt fn getting just a blank screen. Even in booting to repair mode or logging into Xterm, I get the same blank screen.
Lucid with nVidia X at 1900 x 1200 - Had this setup for the last year so Karmic and Jaunty had no issues with xterm. Needing to resolve this to be able to load nVidia drivers.

I recently did an upgrade over the internet from the previous version 10.04. After everything required was downloaded and installed, I rebooted. Now, the system only displays a blank screen after a quick flash of "Ubuntu 10.10".
I have a copy of the 64-bit Desktop install CD of 10.10. I tried to boot up live with it. Same problem.
My system:
K8M800 motherboard
AMD Sempron 2600+
1 Gig RAM
Integrated graphics: VIA S3 UniChrome Pro

anyone has a clue why 'ctrl+a, k' nor 'ctrl+a, :kill' doesn't work for killing one of screen windows? Other screen's commands invoked with 'ctrl+a'seem to work.

I am having the same problem, as soon as X tries to load my screen just goes blank. I have an ATI Radeon 9550. At first I tried switching between VGA and DVI as well but upon ruling that out, I switch to my on-board video card and that is working thus far, but I'm trying very hard to figure out a way to be able to switch back. Anyways I'll check back in later on if I have any new information I will post.

I have 3 layouts: USA, Russian and Hebrew. In Hebrew the W key is mapped to apostrophe, so Ctrl+W in Hebrew layout doesn't close tabs in Firefox. There is no workaround for it as I see by now, so I am trying to get it work this way:I want to map Ctrl+W in Hebrew layout(which is actually a Ctrl+') to be a Ctrl+w. Here is what I got from xmodmap:Code:$ xmodmap -pke | grep 25keycode 25 = w W Cyrillic_tse Cyrillic_TSE apostrophe WAs you can see, there are pairs for each layout, each pair tells what happens without and with the Shift key pressed.

When i use my computer (whether it's going online, typing, playing a flash game, or coding) I get these "Black Flashes" that are becoming longer and more frequent. A "Black Flash" is when my computer screen turns blank (but you can still see the backlight) and i have to press the NUMpad ENTER button, shake my mouse furiously, or click my mouse, which sometimes causes undesired actions, but gets me my screen back. sometimes the Black Flashes last a milisecond or 5 seconds or i have to hold the power button and restart because it won't come back on.

Ubuntu Karmic Koala
2.39 GB of RAM

Is there a known problem with the Lubuntu 10.10 image here? I have downloaded it to two different computers, then burned the images to two different blank CD's (different brands) and neither loads. Both only get as far as the Lubuntu menu, once ENTER is pressed at that point to load the LiveCD, a blank screen eventually appears with a flashing cursor at the upper left of the screen, that's it. They were both burned using the slowest burn speeds available.

The day started as usual until I got the very bright idea to install Ubuntu. A new OS along side W7, that sounded great. I checked some guides on the Internet, it was all very straight forward. Install it and Grub will show you the OS:es when you boot up. I installed Ubuntu, rebooted. After the BIOS messages the screen goes blank and my screen on-button begins to blink, as if trying to find a signal, I press enter, it reboots instantly. After BIOS messages I get to a screen that says "GRUB error: uknown filesystem grub rescue>"
I've looked through everything here and nothing works. I've tried to fix the mbr-thingy using Windows Repair and even though it says "one partition was updated with new boot-thingy" when I reboot, I get into that very same grub rescue. I think my setup has something to do with it. I run RAID0 (2x360Gb hard drives), first having C: at 50Gb and then the rest as F: for programs and such. What I did was that I shrunk the F: part and then used that as partition for Ubuntu. Also please have a look at these screenshots, my partitiontables and such seems completely wacky to the raid: Where should the boot-loader go? I'm very, very new at this. I've had Ubuntu Netbook remix on my netbook for a time but still treat me as an utter beginner.

I fixed this issue on 10.04, but just recently (1 hour ago) upgraded to 10.10 and am having the same issue. Machine boots fine, but the screen is blank for most of the boot, and plymouth is up for about a half second before I get to the login screen.I've tried searching the threads, but for the life of me I can't find the solution and can't remember what I did to fix it on Lucid.

like any other Linux newb, I came to Ubuntu because my Windows crashed one time too many. And I chose Ubuntu because "it just works". But these past few days that hasn't been true. I'm posting this from a netbook with Ubuntu, and am having no problems whatsoever, but normally I use an Acer Aspire 5920G laptop. I'll include the specs as written on the sticker:
* Intel Core 2 Duo processor T5250 (1.5GHz etc)
* Up to 1024 MB Nvidia Geforce 8600M GS Turbocache
* 2 GB DDR2
Let me know if you need more details, and I'll add them later. Now, what happened was I clicked "hibernate" while leaving Firefox open. (I've done this hundreds of times, no problem) And when I went to turn it back on the next day there were weird graphical glitches in the loading screen, and it booted to the "tty1" prompt screen. I did a lot of googling and found quite a few posts about it, but the solutions either didn't work, or I didn't understand them. After trying several different suggestions from this forum and others, I managed to delete the graphics drivers. That enabled me to boot in low graphics mode, and naturally, I tried a whole bunch of things to make it work properly again. That only made it worse. Now it went straight from the loading screen to just blanking out and turning the display off. So, I tried new things. Over and over. The weird thing is even when I disconnected my harddrive and ran from a Live USB, the problem persisted. Could there be an issue with the graphics card itself? Anyway, after reconnecting the harddrive I tried to boot again. And it suddenly worked. Even HDMI to my bigger screen worked.

I have been running 10.04 quite successfully, when I upgraded to 10.10, I have a problem with the newer kernels. If I let it boot into the latest one 2.6.35-23, I get the Ubuntu 10.10 splash screen for a second then a blank screen, same with 2.6.35-22. I have to run with 32-25 to get it to load the gui.
I have an AMD Sempron 2800, 1.6GHz pc, but I'm not sure if it's running 64bit.

I've been running Ubuntu 10.10 very smoothly for a while now. Decided to upgrade to 11.04 - managed to corrupt the hard disk the first time by letting the laptop hibernate part of the way through but reinstalled from a live CD of 11.04 and it's now working except for this issue.
If I shut the screen on my laptop (or press the screen off button) either the screen won't come back on or it will but frozen (I can move the mouse but not click on anything etc.) In this state music continues to play (from spotify under wine) and if I press my hibernate shortcut (power button) the computer hibernates, only to wake into the same situation. I've got a Dell Latitude D520, upgraded to a bigger hard disk and more ram - the ubuntu partition has 50gb. Windows is working fine.
Edit: I noticed a sticky thread which includes something about a blank screen but I think this is a different issue?

I can not copy/paste ctrl+C or ctrl+p from one folder to another with the mouse. i was trying to move an item to another folder.
I looked in the keyboard short cut and it was not there. i tried to add it and it put it in custom as disabled and I could not enable it.

With my first kernel, that comes with Fedora 10 x86_64 installation DVD, I can use ctrl + alt + f2 from desktop, switch to terminal, and log in to any user.
The problem is:
Eventhough the login screen appears as usual with kernels 2.6.27.21-170.2.56.fc10.x86_64 and 2.6.27.24-170.2.68.fc10.x86_64, I can not login. When I enter username and password, the screen refreshes itself to its initial state, i.e., like when i hit ctrl + alt + f2 from desktop. I also tried ctrl + alt + f3, f4, f5 etc nothing changes. Also, I want to remind you that I can login from desktop terminal successfully.

i had slackware 13.0 on my dell vostro 1320 and it was all good, but since the upgrade to 13.1 i cannot change the screen brightness with ctrl+up and ctrl+down keys..i'm not even sure how to start with this problem. from what i understand these keys 'call' a bios function...? so that would mean that some kernel module is not being loaded?or has the desktop environment lost the key mappings and that is causing my trouble?

I just installed Ubuntu 10.10 x64 and already am really annoyed by Firefox, which freezes my mouse after changing a tab (with ctrl+tab, alt+#) or closing it (ctrl+w). After about one second, i can continue working as usual. Changing Tabs by just clicking on one does not freeze anything...Maybe some of you would think now if I am crazy because of complaining about such a little thing, but it is really annoying if you are used to work fluently with ff.Edit:I today noticed, that not only shortcuts in firefox, but all Hotkeys freeze my mouse for a second. For examle ctrl+c, ctrl+v, super+e or anything else.Do you have any Idea what causes this behaviour? Reinstalling ubuntu didn't change anything

Now that I'm more lucid I can adjust the format a bit. If I try opening the TTY the screen goes completely black after visualizing few artifact on the bottom of the screen.
Pressing Ctrl+Alt+F7 brings me back safely to the GUI
So far I tried to modify the /etc/defaults/grub file to uncomment the grub resolution and the grub_terminal to no avail. Now at least it seams to waste some less time to load the grub (it took something like 15 sec before) but it lost the previous green/torquoise background and now it's white char on black background.
On a side note pressing C on the grub to reach the grub console gave me some answer I don't know how to deal with... I was trying to use vbeinfo but it didn't found the command and so I tried the insmod:
Photo(large) of the complete grub console session wrote:grub>
grub> videoinfo
List of supported video modes:
Legend: mask/position=red/green/blue/reserved
grub> videotest
error: no suitable video mode found.
grub> insmod vbe
error: file `/boot/grub/x86_64-efi/vbe.mod' not found
