Ubuntu Multimedia :: Framebuffer In PAL Mode On VGA?
Jan 11, 2011
I have ad724 chip from analog devices that converts VGA signal to composite video, but it requires input in PAL standart. Is it possible to change framebuffer resolution and synchronisation to achive PAL on RGB output? I have try to change this using fbset but there is no change of resolution. Grub runs kernel with framebuffer of 640x480 resolution and i'm able to watch videos using mplayer on cli ubuntu version, but i have problems with setting it up to PAL.Why fbset does not affect to current display?
PS. I have Intel Atom CPU with intel integrated graphics (maybe problem is here?)
I'm trying to get a framebuffer console with acceptable scrolling speed on Dell XPS M1530. It has GeForce 8600M GT card with maximum resolution supported by bios 1920x1200
I've searched and searched and I cannot find the answer. I had links2 -g working in framebuffer in the last release, but in Ubuntu 10.10, I cannot get it to work.
Problem: I do NOT have any framebuffers. /dev/fb0 etc.
I have changed my console font size in grub2 to 640x480 and it works perfectly.
I believe I have all the required framebuffer files and libraries (libs) installed, yet I do NOT have any /dev/fb0 etc.
My monitor recent died and I'm using an old CRT as a replacement for now. I get an error when Ubuntu starts saying it could not find a framebuffer compatible device. It then gives me the option to boot into low res mode which I accept. Once I login, the display actually looks fine, but I would like to get rid of the error message.Anyone know how to remove framebuffer usage from the bootup process? A text display is fine. I looked in my xorg.conf, but I didn't find anything that I could tinker with.
I am trying to install Ubuntu 10.04 in text mode on a VIA EPIA-M motherboard with VT8623 VGA that gives a distorted screen when using the framebuffer. I used to be able to disable the framebuffer during installation by passing debian-installer/framebuffer=false to the kernel, and the screen would be fine. However, with Ubuntu 10.04, I still get a distorted screen even with debian-installer/framebuffer=false.
I set my in-laws laptop up with Ubuntu 9.10 about a month ago as they were growing weary of XP. Everything has gone fine until the other night when my father in law was messing about in software store. He added a few packages, and deleted one by accident. He cant remeber what he deleted, or even which category it was from, but now the laptop crashes when try to start X.
Now when the laptop boots it shows xsplash then goes to a dialog screen which says :-(EE) open /dev/fb0:no such file or directory.Reconfigure does no good, but I can get logged in to text install.The laptop is an Acer Aspire 3630 and uses SiS graphics.I have tried googling to find an answer, but I am at a loss, is there any way to fix this? how would I go about re-installing the full xserver? can I re-install 9.10, but keep the user accounts?
I installed Centos5.2 and have created 1 instance so far. It all works great, but when I created the new instance (using command line from ssh and "virt-install") it gave a message saying probing for video, not found, assuming headless and on I went with the install.
But now I have need for a framebuffer because I have a JBOSS/Java Captcha routine which throws an error if it can't use the X11 libraries or some such (I've resolved this before on a headless Amazon instance once by just running "Xorg"). But I can't run Xorg on my DomU because it can't find the fb device!
So, I searched around and did a makedev -d /dev/fb to create it, but it still doesn't work, because, I assume, the hardware isn't found anywhere. So... how do I get Xorg to work in this case? Or do I need to re-do the virt install and somehow force it to find video hardware (but how?)
Here is some salient output:
root@virty{/etc/X11}: uname -a Linux virty 2.6.18-92.1.22.el5xen #1 SMP Tue Dec 16 12:26:32 EST 2008 x86_64 x86_64 x86_64 GNU/Linux root@domU{/etc/X11}: uname -a
I've just installed Slackware 13.37 x64.Right now, everything is fine! All hardware OK, sound OK, Network/WiFi OK, nVIDIA Proprietary drivers OK, KDE Composite OK, Desktop effects OK.But when initializing, the messages pass very slow!My lilo framebuffer settings are 1024x768x64 (Code 791, 317 in Hex), my Graphics card is an nVIDIA GeForce 9100 M G (256Mb), but yet, I can see it refreshing like an image loading in 56Kbps connection. I really would like to use framebuffer during boot (Oh, come on... The little penguin is kinda neat :-), so I'll ask... Is there a way to use my graphic driver in framebuffer, or make it faster?
I use the CLI a lot (the C+S+F1-F6 terminals), but i have a really tiny resolution on the framebuffer. How do i increase the framebuffer/CLI resolution in suse (that is opensuse 11.4)??
Some weeks ago i hacked a old NCR all in one computer and installed modern hardware inside it, also installed and old VGA 13" B/W monitor inside (supports 800x600 max)
Then installed debian 7 i386 the installer runs fine, the problem is that after finishing the installation the monitor goes out of sync, the kernel load the i915 module and go out of sync.
So I have to connect another modern monitor and blacklist the i915 module, then get back to the internal VGA monitor.now the system boot fine to the linux console on text mode.
I plan to use this system from text mode (no x windows), the problem i found is that because i blacklisted the i915 module i don't have a /dev/fb0 so the console software i like to run like dosbox or scummvm canno't start because the framebuffer is missing.
What i need is to find a way to force the i915 module to a low resolution (640x480). This is what i tried.
vga=ask (or other options) this option is completele ignored by the kernel seem to by deprecated passing grub options to the i915 module like video=VGA-1:1280x800 or modeset=1 also are ignored.
I hope this is not a totally ridiculous question. I use putty often to remotely connect to my laptop at home. I recently learned about the Linux framebuffer, and was curious if there was a tool like putty that would let me remotely connect to my laptop but use the /dev/fb0 device for forwarding graphics. Sort of like a vnc or X11 forwarding, but instead of using X, gdm, kdm etc. we use the framebuffer.
I am a card-carrying member of the Church of the Command Line. I would love to do away with X altogether, and just use the virtual consoles. What's stopping me is, of course, media. Images, movies and web browsing. I know about the framebuffer, and it seems promising but still kind of complicated. From what I've read it looks like I'd have to recompile my kernel everytime I wanted to change the background image. Not a showstopper, but more work than I would like.
Anyway, this post is about the possibilities, and hopefully some hints on how to get started. I know images are possible, and that there are codecs for mplayer to output to the framebuffer. What about web browsing? I've gotten into my gmail via elinks before.. although I can't remember if I was using the standard view or basic HTML.. probably basic HTML. Are things like inline images, javascript, embedded video and flash even theoretically possible in a console browser at this point? Or am I just talking fantasy here?
And, any guidance on getting started would be most appreciated, especially with background images. It looks like mplayer just needs the right codec and it'll work (correct me if I'm wrong please).. so that doesn't seem too bad. But the background images seem kind of involved. The only eye candy I even remotely want on my screen is a nice background image with the text floating on top. How can I accomplish this via the framebuffer?
[Edit: also, I should have made the title more descriptive, but apparently I can't edit that ]
I'm running Linux version 2.6.33.4 on an ARM9 and can successfully copy directly into the framebuffer using the command:
Code: cat /usr/myfile.bin >/dev/fb0
I converted myfile.bin from a 640 x 480 x 24 bmp.
What I'd like to do is to have the ability to dump .bin image files directly into the framebuffer from a C program without shelling out to a cat command.
I am using the most recent -current (that fixes the libpng "ratness" described in the ChangeLog 8-) and the Intel Framebuffer setup is annoying me. I specify vga=normal in LILO and to my knowledge I am not asking Intel Framebuffer modules to load at boot (and intelfb is blacklisted).
It's annoying because it makes the text microscopic. However, the machine works great in -Current so I can't complain. Graphics work fine and so does X, it's just annoying.
This is my Sony Vaio VGN-C140G detailed here: url
I had tried previously blacklisting inteldrmfb as well (the -Current release right before the libpng fix) and that made no difference.
I found all binaries with "intel" in their name and read the manual pages but didn't find anything useful for possibly manually setting the mode back to something equivalent to vga=normal.
I'm installing a non-X server using squeeze 32bit netinst iso, expert installation. I don't know that I can specify "debian-installer/framebuffer=false" during the installation, after reboot I got a framebuffer display with console fonts smaller and fonts look like ubuntu. I search around I can edit GRUB config for the resolution items or disable framebuffer. How can I disable the framebuffer (use normal text system fonts) when booting in LILO?
I got everything installed and setuped, I don't want to re-install the OS again.
Kernel parameter vga=0 or vga=normal does not work as expected - First it works as expected text mode resolution is 80x25, but after some seconds the kernel, or the initramdisk does switch resolution of console again! I hate to say but it looks like OpenSuSe (again) thinks it is more clever than the user.Since rmmod radeon in runlevel 3 says "ERROR: Module radeon is in use", I do think that somehow SuSe ignores my vga=0 ... Is it the kernel or the ramdisk, I do not know where to search, since the parameter vga=0 is accepted and used in the beginning - it switch again after "doing fast boot" or 1-2 lines later..
Just upgraded my system from 13.0 to 13.1 Most things went pretty smoothly, but I tried 'startx' before the post-upgrade/config reboot and the system hung - "time to upgrade my video drivers", I thought. Upgraded to Nvidia 195.36.15*. X works perfectly, and a modprobe shows the 'nvidia' module loaded. So far so good.
However, when I try to use any vesa modes in lilo, I get a blank screen after the BIOS check and the system hangs - even toggling numlock on or off won't work... So I can only boot up in text mode. This makes me unhappy, partially because I like penguins, but also because it is an absolute insult to my new (old) monitor. I thought this could be to do with the nouveau conflicts reported by -current users some days ago, but the respective blacklist file is present so I'm stuck as to what to do... *I've tried 195.36.15, 195.36.24 and the latest 2xx beta drivers. All exhibit the same behaviour.
EDIT - forgot to post my video card specs. It's an 8500gt w/ 256mb, 128-bit DDR3.
I am using 11.4 32 bit Gnome. It is working fine expect high CPU usage. Specially by X-ORG. I am running this on my old PC with core2duo, Intel motherboard DG31PR, Integrated Intel GMA 3100 Graphics(intel G31 Exprss chipset) , 3 GB RAM I went to Hardware information in YAST and found some discrepancies.
1. desktop board is listed as D945GTP instead of DG31PR 2. in framebuffer 1440 X 900 is not listed which is my monitor resolution 3. BIOS info has no vendor name

I'm using the 270.41.19 nvidia properietary driver for my Geforce GTX460 graphics card. I have a Sony TV connected to my HDMI and I know it supports the 1920x1080 resolution. Yes it works after gnome or other DE loads up.
But during the GRUB screen and the bootup console - It defaulted to a 640x480 resolution (as it always does with the nvidia prop driver). I usually used to check the output of hwinfo --framebuffer and choose the resolution by appending the right vga=0xabc parameter.
But now I have a problem since hwinfo says the best widescreen 16:10 framebuffer resolution that my card supports is 1280x800. Here is the output from hwinfo --vbe which should give the info about both my gfx card and my TV.
The initial nouveau driver was able to output native 1920x1080 during the bootup on the console without issues, so I guess even the properietary driver should be able to output (If my understanding is right the nvidia module loads later during the bootup and only is required for the X but not for the console itself).
I have a NWZ-e344 Walkman and I'm trying to to get it into mtp mode. I have created a .mpi file that that shows the Walkman as a music device instead of a flashdrive.
While in root account it shows up as a mtp device but not in my regular account how can i get it to read as a mtp device like it does in root in my regular account?
Got an Asus eeepc 900a. Runs Intel 915 graphics. Upgraded to slackware current last week. X would not start. Based on info here, I reverted back to earlier libdrm and xf86-video-intel. That got it working again.
Updated Slackware current again today. I think I got a new kernel. Now, halfway through boot time, the screen goes blank, then comes back and the font is tiny. Gone into framebuffer mode. If I start X, it just freezes. Nothing but a reboot will get out of it.
I have vga=normal in lilo.conf, but I read that this is no longer used. I can find no way to turn off framebuffer mode. From other threads here, I have tried append="i915.modeset=1" in lilo.conf. Has no effect.
I could revert Slackware to 13.0 from current, and that would make the eeepc useful again. Is there anything else I should try?
This started yesterday.I have been running Lucid since the Beta release with no problems. Yesterday, I found about 20 or so updates ready for 10.04. I looked them over, mostly lib files, so I decided to go ahead and let them update. That evening I rebooted my machine before I left for the night, and it came up with the error "Ubuntu is running in Low Graphics Mode". In a word X is totally hosed. The display is cut just left of center, with part of the windows on the right carrying off the screen to come back onto the screen to the left.
I thought maybe Xconf might have been messed up, but not sure how. The updates I applied did not do anything to Xorg; and my understanding was that I didn't need that file because I am running with an Nvidia card. I tried to "reconfigure" the X settings from the error message, that did not work. I logged into a text only terminal, and copied a good backup of Xorg.conf back into place and rebooted. Same thing, still running in Low Graphics mode.
Disclaimer: I have very little linux desktop experience...I've only used command line stuff for work in my previous life. I am joyfully coming off of a long addiction to MS but am having a bit of a hard time adjusting.
ISSUE: I can't seem to figure out how to turn off suspend mode. I have turned every setting I could find in the power management to "do nothing" and I have turned off all of my power mgmt options in the system bios. A "friend" suggested I remove HAL...which caused me to lose my secondary internal HD and all of my usb devices...and the issue persisted. Every 20 minutes of no action the screen blanks and my monitor goes into standby mode which is making watching movies in bed a less than relaxing experience.
Some background that may or may not be useful: I installed kubunutu 10.04 (2.6.32-28-generic) from cd on a fresh HD. Initially I had issues with the wireless network and alsa/pulse sound. I worked through those through much trial and error but the suspend issue persists. I've uninstalled and re-installed lots of packages I probably shouldn't have been messing with and would really like to avoid a reinstall as this seems to be the final fix I need to get things running the way I want them.
After making and update my Karmic Koala and trying to set up lamp through tasksell, i have rebooted my notebook. Then the ubuntu logo was displayied and i get an"Ubuntu is eunnung in low graphics mode"(EE) open /dev/fe0: No such file or dierctory.i have done some googling and figured that it has most likely to do with ubuntu tryin to using frame buffer wrongly.
I followed the wonderful guide in this section with all of the steps and whatnot (I forget what it is called) and I got my DVD player working. I have used both the built in DVD player, and VLC with all the required codecs and whatnot. But when I go to full screen, the player (both of them) crash and I have to eject the disc and start over. It is actually kind of weird because I can resize it larger to a certain extent, but I feel once it gets over about 50-75% of the screen, it crashes.
last week I did an update and it may or may not be tied to the fact that now I can only login to Failsafe Gnome mode. I'm running Ubuntu 9.10 - Karmic Koala. I've had Ubuntu for a year but I'm not that familiar with it.
I am trying to fine tune the S-video output settings for my xubuntu box running 9.10. I am having some trouble getting modes loaded via xorg.conf. Currently, my xorg.conf file looks like:
After installing Ubuntu 10.04 LTS over the weekend I had some problems, which I subsequently solved and thought I'd mention here. - First, the dreaded Low Graphics (EE)NOUVEAU(0):Error allocating scanout buffer:-12 which wouldn't allow me to change my monitor resolution. - Second, TVTime television viewer would not launch at all.
Solution to BOTH of these problems: From Synaptic uninstall xserver-xorg-video-nouveau (experimental) and reinstall xserver-xorg-video-nv. Now everything works!
