Ubuntu :: How Does Karmic Set Text Console Screen Resolution
Jan 21, 2010
I'm trying to track down a screen resolution issue (Karmic on an Acer SK20 [Intel 945 graphics] with Acer AL1511 flat panel via VGA) and mechanism for setting the framebuffer screen resolution after GRUB2 has loaded the kernel but before X starts.
Before I forced it to behave itself by adding an xorg.conf with a lone "Modes" entry for 1024x768, X was setting the panel to 640x350 by default. It appears from looking at get-edid | parse-edid that this is because 640x350 is the only resolution this idiot panel's EDID says it knows about, even though its native resolution is in fact 1024x768.
So the GUI works fine now, but all the text consoles (Ctrl-Alt-F1 through F6) are still operating at 640x350 and look terrible; also, because usplash doesn't know what to do with 640x350, I don't get my nice white Ubuntu logo before GDM starts.
In previous releases, I would have dealt with something like this by adding vga=791 to the kernel boot options. That doesn't work for the Karmic kernel, and GRUB2 whines about it being deprecated and tells me to use "set gfxpayload=1024x768x16,1024x768" on a line before the "linux" command instead.
Things I have already tried, with no success:
1. Adding "set gfxpayload=1024x768x16,1024x768" into the boot sequence, right before the "linux" line, by using GRUB2's inbuilt boot sequence editor (Ctrl-E): no change.
2. Changing the GRUB_GFXMODE= line in /etc/default/grub and running update-grub: changes the resolution used for GRUB's own menu, but as soon as the kernel boots it's back to 640x350 on text consoles.
3. Same as (2) but also adding a "set gfxpayload=keep" line in /etc/grub.d/00_header, right after the "set gfxmode=${GRUB_GFXMODE}" line: same effect as (2).
4. Removing the "splash" option from the "linux" line. No change (I guess this is because usplash didn't work anyway at 640x350). By the way, usplash.conf is set up for 1024x768 and yes, I did remember to dpkg-reconfigure -phigh usplash to rebuild the initramfs after checking this.
where exactly does Karmic set the screen resolution for its text consoles, and how can I force it to ignore this LCD panel's bogus EDID?

I have install Fedora 13 on my machine (Intel 815 Chipset with graphic card of nVidia GeForce 256), but the default resolution of text console wound have be about 1024x768. I intend this machine as a simple samba server (without X Window), so just a low-resolution monitor will work with it. However, this monitor can't work with the resolution higher than 800x600, I have to change the resolution lower. I have searched the solutions for this problem on Google. Most of them thought I should fix /boot/grub/grub.conf, append "vga=769", "vga=771" or even "vga=ask" to the end of the line start with the word "kernel". I have tried but all of them doesn't work. Just like Fedora 13 use the value from the other configure file overwrite the one list in grub.conf. As everyone knows, if I installed and launched X Window on my machine, I could query and change the resolution with command "xrandr". Are there some similar ones that can work on text console?

On the 28th of April I upgraded my system (laptop with "SIS Mirage 3 Graphics" video card) from Karmic to Lucid and my screen resolution was reduced from 1024*768 to 800*600. I tried during one day to find the suitable driver but no luck on SIS web page.
I eventually found it on the followwing address : [URL]
It works very well and the resolution has jumped now to 1280*800. The only remaining and identified problem is with grub2 : my system is dual-boot (Windows XP and Ubuntu) and the "recovery" mode does not work anymore for ubuntu, I will maybe have to wait for a next update.

One thing I loved when I checked out the live cd of Lucid was the fact it had a nice drop down list with lots of screen resolutions to choose from, does Karmic have that same feature?

I am using Ubuntu 10.10 on a Dell Optiplex GX270, with the Intel video chip. I have a problem with my virtual consoles/terminals (<ctrl-alt>F1-F6). The default screen resolution was set to 1600x1200 at installation, which results in a nearly microscopic, unreadable font. I posted the problem on this thread on ubuntuforums.org, where they suggested adding GRUB_GFXMODE=640x480 and GRUB_GFXPAYLOAD_LINUX=640x480 to /etc/default/grub and /etc/grub.d/00_header. Still no joy--the console screen resolution still was 1600x1200.
I have noticed that the screen resolution changes three times during boot; it starts at standard VGA, 640x480, then switches to 1600x1200, then finally to 1024x768, which is my preferred resolution in X. But, if I switch to a virtual console, the resolution shoots up to 1600x1200 again. There are times when I like to use virtual terminals, and I would like to avoid eyestrain.

virtual console (run level 3,5) screen resolution. After installing fed12 the resolution is higher(which is good) then in previous versions. After upgrading from 11 -> 12 the resolution of the virtual consoles stays the same, to large. I already compared grub.conf,i18n which are the same. Where is the resolution configuration for fed 11,12?

After install of FC13, my command prompt console and tty virtual consoles are a small box in the upper left corner of the screen. It contains tiny 80 characters by 25 rows. I want to fill the screen the old way. I assume the problem is high value screen resolution set automatically to match my display; with fonts based on the smaller pixels. This is NOT X-Windows. I can set that resolution but it has no effect on tty consoles.
It is NOT grub, which I can set with kernel parameter vga=0 to do exactly what I want. Messages from grub are big letters but change to tiny ones at init ("press 'I' for interactive startup" and the beginning of the boot log). This is not an issue with the same display using FC10 and no vga= parameter. Is there a reason that the kernel parameter failed after grub? Can I specify console resolution?

I have tried this with many different configurations, however, I believe that the scroll bar that shows the progress of the boot is preventing it from changing successfully. I don't know how to switch it off. X is not installed. No gui, only tui.

I booted Hardy, because Karmic detects no screen, after trying to adjust to a previously recognized resolution. As good as it is, does it seem like some basic computer functions just do NOT improve?

I have been running Ubuntu 10.04 on my laptop just about since it came out.Prior to that I was running 9.10 on the same laptop. I was so happy with 9.10 I thought I could only be happier with 10.04.I was wrong.There are some things about 9.10 that I have *lost* in the transition to 10.04.These bother me quite a bit so much so that I have repeatedly considered going back to 9.10.Please keep in mind this all worked fine under 9.10 on exactly the same hardware.
1) When I connect the external VGA port on my laptop to my 32 Samsung TV it comes up as a 40 Samsung TV and it is impossible to set the correct resolution.This makes watching TV over the Internet via my notebook impossible (I used to use URL... and others).
2) I cannot change the resolution on the console (the TTY's 1 to 6). It used to come up as standard old fashioned VGA (80 columns by 25 rows of text) but now it is much smaller font and much larger console.The VGA= in GRUB does nothing. And this is the only suggestion I seem to be able to find. From my reading most people seem to like the large console w/ small font.I dislike it for the reason I will get into next
3) DOSEMU locks up my computer with a blank screen when running in super mode on the console.Pressing Ctrl+Alt+F# accomplishes nothing and either does Ctrl+Alt+Del.I have to press and hold the power button forcing a hard shutdown (at least this is the only solution I have found).

I'm looking for software which will allow me to record a screen-cast of a terminal based application, recording keystrokes, timing of keystrokes, and audio. I see a couple of advantages to this approach over video capture: Display independence: the viewer can display text in any resolution/style they want, not limited to the resolution of the recorded video. Ability to copy and paste text from the screencast.

Let's start with some context: About a week ago, I saw in the university computer that the text mode consoles(ctrl+alt+f[n]) worked with a great resolution on a 19" wide screen (I think it is 1440x900) running fedora 11. So I wondered if I could make the text consoles at home to work with a good resolution also.So I started to search for that and found the kernel parameter vga= . The problem: it doesn't support 1440x900 or any other 16:10 resolution for my graphic card. Then I thought that maybe fedora uses some module that allows that, because the livecd allows a good resolution (by default) on my desktop computer.
What I thought so far is that fedora is not using vesa for the virtual console (which i think is the driver that ubuntu uses) and I want to know what driver it is and how to use it in ubuntu (either compiling the kernel or simply installing something).I don't even know if my guesses are right or not. But I've gathered some info so far:From /var/log/messages (fedora 12 livecd) I got this part, which I think is the really interesting one.Quote:
Mar 2 22:37:18 localhost kernel: [drm] Initialized drm 1.1.0 20060810
Mar 2 22:37:18 localhost kernel: [drm] radeon defaulting to kernel modesetting.
Mar 2 22:37:18 localhost kernel: [drm] radeon kernel modesetting enabled.

I debootstrapped an install into an existing lvm and booted into it and everything is working great except that after initrd hands off to boot the real root, the text font changes and the resolution is unsupported by my old monitor. The box is up and running because I can ssh in. This is more of an annoyance than anything as I only use the console when something is broken, but it does need to be resolved.
I used dpkg-reconfigure console-setup as described in the debootstrap config guide but I don't see an option for changing the "vga" statement before it regenerates the initrd.

In vm workstation console resolution default is 640x480 ,and i want to change it to 1024x768.
In Debian7 , it can changed use vga=792 in /boot/grub/grub.cfg.
But in Debian8 use changed use vga=792 in /boot/grub/grub.cfg , screen will all black.
Although screen can't see anything , but it can connect through ssh normal.
I also tried GRUB_GFXMODE=1024x768,GRUBGFXPAYLOAD_LINUX=1024x768 in /etc/default/grub , it get same Result.
I don't know the problem is at VM workstation or Debian 8.

playing with debian I find that I have no answer when I try to resize my console if I wish to use it without a GUI. Are there something that could resize the screen ? In this moment it seems to be 640x480 and it could be better if the resolution could be 800x600. I have tryed to modified /etc/grub/00_header
if [ "x${GRUB_GFXMODE}" = "x" ] ; then GRUB_GFXMODE=800x600 ; fi

I just upgraded from 9.04 to 9.10 then discovered that, in openoffice.org-writer, the text in the UI is gone. It's strange because the text to be edited is still there. So maybe it's a font or rendering problem but I suspect something related to the window manager is going wrong. I have checked and re-installed openoffice but I haven't been able to fix this so far.

I'm running Ubuntu 11.04 on an IBM Thinkpad T60, when I try to Logoff, Restart, or Shutdown the system just goes to a black screen and I'm forced to do a hard reset to restart the system. I did a reinstall and things seemed to be working fine until I applied updates and reloaded my package list from my previous install then I got the same conditions as before. I suspect that this my be a result of a bad package or update. What I want to know is if their is a way to display console text of the shutdown process so I can see where the system hangs and possibly remove the problem application. I have an AMD 64 bit desktop running with the same package lists and have no issues I suspect it is a hardware specific issue for the laptop or an error with a 32 bit install.

I am have upgraded from 9.04 to 9.10 in my laptop. After performing the reboot, the shell/console resolution went very high and the font size went too small. How to regain the old console shell resolution as in 9.04. I require this urgently as my laptop suffers the white screen problem. Switching between Ctrl+Alt+F6 and Ctrl+Alt+F7 I could get back the screen as the change in the resolution switches off and on the screen, so that I can negotiate with the white screen problem.

I am running Lenny of a Dell Mini 10, using only the console. I want to get the resolution smaller that 80 on the horizontal axis, but I can't find the right setting for vga in /boot/grub/menu.lst.
Inserting various values makes the dell give me list of possible video modes at boot, but none of these are higher than 80xSomething. It offers VESA modes that are choosing these results in unreadably tiny text, and anyway I wouldn't know how to edit in order to make these mode take effect automatically.
Can anyone tell give me a value that works for vga on Dell Mini 10 that produces a smaller resolution that 80xSomething? If not, can someone suggests a different way to obtain the same result?

using Ubuntu 10.10 amd64, my older NVidia card suffered a hardware failure last week, and so I replaced it with an NVidia GTS 450.
As the driver that was previously in use was nvidia-173, at the next boot with the new card the X server didn't start. I got to the text console, where the /var/log/Xorg.0.log had the message that the GPU/chipset is unknown to the driver. (well, ok )
Some web searches revealed that the chipset GF106 of the GTS 450 is only supported by the NVidia 260.19.12 driver, which is not in the Ubuntu stock repositories, so I followed the instructions at http://halvar.at/blog/?p=258 to install the latest driver from the PPA repository:
sudo aptitude install nvidia-current
sudo add-apt-repository ppa:ubuntu-x-swat/x-updates
sudo aptitude update
sudo aptitude full-upgrade
In short, although all of the above worked fine, the problem is that even after a reboot, the system still uses the nvidia-173 driver (according to Xorg.0.log, and starting X still fails).
Before I tried the above, I also tried
sudo aptitude install nvidia-current
alone, in order to get the latest driver that is in the stock repositories, but the result is the same in both cases.
What do I have to do in order to activate the nvidia-current driver (either stock or from the ppa above) instead of nvidia-173??
I tried to modify the proper blacklist file in /etc/modprobe.d/... (sorry if the file names are slightly wrong - I'm typing all this from the top of my head, as the affected Ubuntu system has no graphics, and thus no graphical browser etc. ), but then there is the error:
"Error: API mismatch: the NVidia kernel module has version 260.19.12, but this NVidia driver component has version 173.14.28 ..."

When I try to load Ubuntu (recovery mode) or if I press Ctrl+Alt+F1, the image gets corrupted showing a white screen with black writing on it, but which is unreadable. Also the words seem to be spelled backwards. I'm trying to install an NVIDIA driver and I need to stop first the X server.

I have just come over from the darkside (Microsoft) and am finding problems with a few items.
I am trying to configure the monitor/video card as I am having problems with the nvidia geforce 4 integrated video card. Some instructions I have sat to press ctrl alt and f1 to go to the text console. I do but it asks for a login and does not accept my user name and password.
What have I done wrong?

I've been scouring the internet for an answer to this problem. I am using Squeeze and have properly configured Grub2 to set my console screen resolution to 1024x768x32 (as per updating /etc/default/grub to contain 'GRUB_GFXMODE=1024x768x32' and updating /etc/grub.d/00_header to contain 'set gfxpayload=keep') and everything works wonderfully. My resolution is set as it should be. However upon installing Xorg (aptitude install xorg ratpoison), my console resolution gets changed to what appears to be 1280x1024.
I thought that this was due to xrandr, however when I issue:
# xrandr -s 1024x768
only the X resolution is changed. When I then CTRL-ALT-F1 back to the console, the resolution is still at 1280x1024 (I am aware that xrandr only affects X, but I assumed that because my console resolution was correct before installing X there might have been some correlation).
I would like for my console resolution to stay at 1024x768 as per Grub2's configuration and for X's resolution to be at 1280x1024.
PS I also noticed that prior to installing Xorg, my CPU boots up without any screen blanking (only for a second or so). However, after installing Xorg, during the boot process the screen does blank briefly. It is at that time that the resolution gets changed to the 1280x1024 setting.

I'm using Fedora 10 x86_64 with an ATI Radeon Mobility x1400 video card. Before installing fglrx & compiz, the text console (while booting up) was shown at 1280x800 resolution (laptop widescreen). After installing fglrx & compiz the console would only show up as 640x480 resolution. My resolution in X starts as 1280x800 without any problem. I realize that you can use vga=xxx as a kernel argument but this only works with NON-widescreen resolutions. I require that it be set to a widescreen resolution like it was before the fglrx & compiz installation.

fixing a text corruption issue / advice for filing a bug report (if necessary). So, generally speaking the stability I am experiencing with Natty is as I expect; I'm fully aware that this is a very very early development release and so all sorts of things can go wrong. I just wanted to point that out So while Gnome/Unity are up and running, graphics run more or less perfectly, the boot process text is completely garbled and if after everything is fully loaded I hit Control+Alt+F1-F6 the text looks like:
* this
* the above image close-up
The above links are supposed to be of the ubuntu login prompt. The problem occurred after running the upgrade command:
Code:
sudo do-release-upgrade -d
As is standard upgrade procedure. Is there anything obvious going on that I can tweak to make it all happy again? Since I have a working GUI.
