Ubuntu Multimedia :: Blurry Projector Image With Intel GMA
Oct 11, 2010
Here are the details:
Acer Aspire 5315-2681 notebook
Intel GMA 965 adapter
Ubuntu 10.04.1 (Lucid)
Not sure what resolution the desktop is, but should be 1280x800
Fn+F5 does nothing (2nd display notebook hotkey)
ANDsome sort of SHARP projector
Projector resolution should be 800x600
(There is a sticker on the computer that says Mobile Intel GMA X3100, however.)
When I booted up the computer with the projector attached my bootloader appeared on the wall but not on the LCD. When I logged in my desktop appeared properly on my computer and is duplicated on the wall. However the wall image is very blurry. Part of the lower image is cut off and the right side is too short and there is a green band on the right edge a half dozen pixels wide.
When I booted (dual boot) into windows XP I got the same thing. Then I installed the proper drivers for the graphics adapter (they had not been installed because I hadn't used XP for anything but updating the BIOS) and the image lined up neatly and fit properly, and I could set the display to extend my desktop (instead of duplicate) it on the projector image. (This is what I would like to do under Ubuntu).
I'm concerned that my VGA controller doesn't have the right drivers or is set up incorrectly, but since I'm new to Linux I have no idea how to fix it.
There's several threads dealing with overscan, but I've got an interesting twist in my setup that (I believe) is putting a kink into the proposed solutions. I'm trying to set up a media center PC with Ubuntu 10.~. The motherboard has built-in ATI graphics (3300 series), and connects to my television (Panasonic capable of 1080i) via HDMI. As can be expected, the overscan makes the top and bottom bars nearly invisible (as well as a portion of the sides).
When I run the Catalyst Control Center, it informs me that the monitor is a projector, not a TV. Try as I might, I can't convince the thing it's attached to a TV. When I run "aticonfig --tv-info", I am informed that a TV is not connected.
One question I could ask, though: does it matter? The reason I'm asking is that I can't find the "Configuration" menu option in the CCC that all the other threads talk about. I know where the little black triangle menu is, but there's no "Configuration" item in it. There's also (as best as I can tell) no way of adjusting overscan for a digital projector.
Ubuntu 10.10Asus UL30Agraphic chipset Intel GMA 4500 MHDNative LVDS1 display resolution is 1366x768, but my laptop now boots at 800x600. Using xrandr to set resolution at 1366x768, I get the right dot pitch but the screen is still 800x600 px wide, left-top aligned on a 1366x768 display, so that I see a 168px black belt on bottom and a 566 black belt on the right. A vertical screen offset of 168 px affects also the pointer (touchpad) in the following way - I can move and see the pointer arrow all the display wide including the black region, but input (click) is taken for a position 168 px above the pointer visible position.
This is happening after having used the laptop with an external projector and gtkwhiteboard (wiimote based infrared pointer management). I then removed gtkwhiteboard to no effect.Everything works fine when booting in failsafeX, recovery mode. Here is output of uname -a
Code: Linux bidolino 2.6.35-25-generic #44-Ubuntu SMP Fri Jan 21 17:40:44 UTC 2011 x86_64 GNU/Linux
I need to clone my laptop's desktop in a vga projector. I'm using debian 8 kde spin. If I simply connect it, the projector become the extension of my desktop (like dual monitor). Of I go on monitor setup in kde settings, I can just enable or disable One of 2, or setup the main, but there si no option to clone from the laptop to the projector.
I have a problem with the graphics on my thinkpad a22m laptop. specs:
900mhz cpu 256 ram 20gig hd ??ati rage mobility m3 video card ??
when I start up ubuntu (10.10) and reach the desktop, the screen is messed up. The center of the screen becomes blurry, and it looks like what is normally the right part of the screen is duplicated in the middle of the screen (with what should be the middle of the screen disappearing).
I think its an ATI video card, and I tried to install different driver from Softwarecenter but no succes.I know the screen is working, because when I boot forinstance, the Ibm logo is showed nicely across the screen. So its not a hardware issue. Another thing, I got puppy linux to work correctly after having the same grapphic issues on that OS when I first installed it. But some how I managed to get the right drivers. But as I like ubuntu more, I would appriciate your help with figuring this out
ps. when I try to setup screen resolution in System>Settings>"resolution", Ubuntu says "unknown display" (marked with red color).
Yesterday I was trying to connect the overhead projector to the VGA output of my laptop. The problem was that the device was connected by way of a VGA video splitter, which evidently missed some signal, and made the projector invisible to the laptop: "xrandr -v -q" told me "VGA1 disconnected".
The solution is: boot with
Code: video=VGA-1:e kernel boot parameter, found in the wiki and in intel linux FAQ.
It works, but it is a bit awkward to have to reboot to switch on or off the VGA output. So I suppose there is some user-space trick or utility to do this which I was unable to find.
If your PC has a 64-bit AMD or Intel processor, you will most likely need the "amd64" images (though "i386" is also fine), the "ia64" images will not work."Does it mean I should use ia64 image for my 64-bit intel processor?
Can someone tell me what the architecture of iMac Intel Core 2 Duo is? I am trying to figure out which of the following images given on the webpage below to download:[URL]..This is the list:
I think there are two different images (namely i386 and ia64) for intel-based systems, right? Which one should I download for my Intel Core 2 Duo? Is this a 64-bit architecture? Should I use amd64?
When playing dvd's, vob files and wmv files, the image comes with high contrast colors ,very intense red/green/blue. very dark too. I have vlc 1.1.4 installed, using ubuntu 10.10, libdvdcss2 installed. for the rest of the video formats it seems to work fine. any ideas on what should I start debugging?
I have recently installed Ubuntu 10.10 on my computer. The default display driver supplied with it only allowed the screen's default resolution (1280x1024), so I downloaded and installed nVidia's latest driver (260). When I change the resolution to anything lower than the default, the graphics (and most notably letters) everywhere appear slightly blurry, becoming more and more blurry as I lower the resolution. The blur is not terrible, I can still use it but it becomes annoying to watch after a while. I am using a GT240 graphics card, and this problem does not exist on Windows using the same resolution and same driver version.
I have a new laptop where I had to install Ubuntu 10.04 (8.04 wouldn't boot). All Mozilla software that I use every day (Firefox, Thunderbird, Sunbird) has blurry fonts in 10.04, as opposed to 8.04 where all the fonts are clear. I remember that on 8.04, Thunderbird 2 has the same blurry fonts if I use the package from Mozilla's website, but the fonts are clean if I use the Thunderbird 2 from the repository. The fonts in the content rendering (mail, web pages) are also blurred in a similar fashion in 10.04. I attach here the menus from Firefox 4.0 beta 1 on 8.04 and 10.04. It can be seen on large zoom that the fonts are not only blurry, but slightly smaller in width.
Im looking for magnifying glass functionalty for ubuntu. I want to use it for web design: watching icons, borders, spaces, etc. I tried the compiz zoom, enhanced zoom and mynifying box bout all of them make things blurry and I couldn't find the way to make things "sharp". Is there such an option for those plugins or an alternative way to have that functionality?
A friend whom I turned on to Ubuntu with 9.10 recently connected a projector to watch a movie off her laptop. When it was connected, the laptop screen changed and it was clear that desktop effects through compiz were disabled. Thing is, since disconnecting the projector, I cannot get the effects back.If I go into Preferences - Appearance and click to enable Normal or Extra Visual Effects, the same thing happens. I.e. I get a popup saying Searching for hardware driver...and after about 20 seconds, the screen flashes a bit, and says
Desktop effects could not be enabled. Not sure why it's searching for a hardware driver. The computer doesn't require any 3rd party hardware drivers to be enabled - it doesn't have an nVidia card or anything like that.If it makes a difference, she yanked the VGA cord out without setting the display mode back to just her laptop with the FN and F key combo.I've tried:
-Reinstalling compiz
-Tinkering with options under Preferences - Display
-Ensuring that nothing is available under Preferences - Hardware Drivers
I am trying to communicate to a Sanyo projector using pySerial and am having issues. I have verified that my baudrate and parity are all set correctly. Here is my code (using COM13):
import serial ser = serial.Serial(12) ser.baudrate = 19200
[code].....
I have also tried variations using "CR0", "CR0", "CR0x0D" and nothing seems to change it. I'm using another application to ensure that I can speak to the Sanyo projector, and I get a correct response.CR0 is a status read of the hardware that should return something like "80" which would mean "STANDBY"However, the responses that I keep getting are things like 3,4, or 5 which seem to be errors, given that they are returned apparently based solely on the length of the String I send, not based on the actual command.
I've been using Crunchbang for a little while, and I've started to notice that I'm actually having to squint to see the text on every site (as well as the text used in the menus). What's weird is that these same sites look great in Ubuntu (I can actually see them and what not), but for whatever reason all of the text is blurry in crunchbang.
Generally on my system(Karmic x64), if I generate a pdf, any image included comes out distinctly blurry. I have googled and come across this [URL] which says when there is a pdf generation, everything is recompressed, hence the blurriness. How is there a way around this? What do I tweak to ensure pictures are left alone (I already ensure they are as small as possible) when I convert anything to pdf?
I installed the fglrx drivers in Ubuntu Natty for a ATI Radeon HD 4350 graphics card. Although compiz seems to work better, everything seems to be a blurry as compared to the generic graphics or while under Windows 7.For example, every other line displayed here while I type is more blurry than the others.I have a dual screen setup.
When I connect my laptop to projector, its not detecting. But when I log-off and then log-in it automatically detects the display. I tried function key, but its not working. I am using Debian Lenny also. Also several others with different version of ubuntu running on different laptops reports the same problem. I tried searching net, but couldnt find a good answer.It would be helpful if some one explains what exctly is happening and an easy work around for this problem.
There's a quality issue here i'm sensing. WHen i zoom icons while in Dolphin, the icons are quite fuzzy. I think it's when it reaches say 128x128 i'll estimate.It's really strange because in Mint 9 KDE, oxygen icons show cleanly at max zoom :/ How can i fix this?
i need to connect my loptop Vaio F116FG to projector with VGA cable.now when i connect them in suse,projector doesnt show loptop image,and loptop doesnt know projector.(in windows 7 its work fine)
My Graphic card is Nvidia G330M,and its driver is installed
I'm having problems installing or removing anything from Debian. The whole problem has kind of looped for me for half a day now.
I installed Debian with the latest release and when I booted into the system, everything was working fine except the screen was blurry. So I spent a few hours looking for a way to install nvidia drivers. Trying to used the nv drivers, (vesa before) caused gdm to stop working with "no screen found" errors and when i finally installed the nvidia drivers, it seems to have reverted my kernel back. I was at 686 before and now I'm on 486, giving me an extra option between 486 and 686 in grub.
This was fine to me but when I boot into the 486 I get notifications about updates close to a gig in download size. I didn't want to download it in fear of breaking the system but did after package manager would refuse to install or uninstall anything without installing/uninstalling the gigs worth of updates.
During the update, my screen kind of malfunctioned and i rebooted going into ctrl+alt+f1. When I came to, the gdm wouldn't start, kind of looping to the login screen and blanking out, never fully drawing it. I tried a few configurations in /etc/X11/xorg.conf to no avail and decided to try the 686 configuration.
Xserver wouldn't boot with noscreens found untill I decided to try to install the same nvidia drivers. While I was still on the 686 kernel, it would not boot but when I rebooted and went into the 486 kernel, it logged back in to what seemed before updating.
My display on fedora 13 freezes, key board stops working, when I connect projector to my laptop. I see the display settings mentions "DVI monitor, resolution 1280X800 refresh rate 60.0". Do I need to set the resolution to some other number before plugging the projector on and do I need to change it back to the default resolution after unplugging projector
I have installed fedora 8 on my cPCI based system [URL]. It seems to have 256MB RAM. Once I login as root in text editor mode, I typed init 5. But the graphical display appears very blur. I changed the monitor, but still same result. One more observation I made is, after 10mins it used to enter into screen saver mode (blank screen), but when I pressed some button, the graphical display appeared with full colors. But now even this is not happening. The system just goes into some state after init 5, where my the display goes blank and even the keyboard doesn't work.
I have an Intel server, which has it's two SATA HDD's in "Intel Embedded Server RAID Technology 5.4" RAID1 volume. How to proceed with a system image in case two of those SATA HDD's fail at the same time? Should one take the first HDD of RAID1 volume, connect it to another machine and execute:
Code:
# ddrescue /dev/sda1 /media/External/image_of_first_hdd /media/External/log_of_first_hdd * HDD from the problematic RAID1 volume would be recognised as /dev/sda1 behind new machine * /media/External/ is a mount point for large external HDD in the new machine * log_of_first_hdd would be the log file
..and then take the second HDD to another machine and execute:
Fedora 13, x86_64, up to date. Trying to get nVidia Quadro NVS 140M to display on a projector the same as it does on the laptop screen, which is 1680 x 1050. I failed to do so with the nVidia driver (latest version), so I want to go back to the nouveau driver and try with xrandr. I have always used the nouveau driver with Fedora without an issue, but in my former life in Ubuntu I sometimes switched back and forth between the "nv" driver and the nVidia driver.
Doing so was trivially easy - just edit xorg.conf replacing "nv" with "nvidia" or vice-versa, then restart X. However, after installing the nVidia driver via Yumex and using the nVidia config utility, I find that now I have an xorg.conf file that is loaded with stuff I don't understand, except that at the top it says it was created by nVidia, and there are two places where it says the driver is "nvidia." I have searched and all I can find is instructions for installing the nVidia driver.
Apparently that is meant to be a one-way ticket, because I can't find any instructions for how to return to the nouveau driver. Except stuff that is over a year old, and complaints from users whose systems failed to start X. What would happen if I just replace "nvidia" with "nouveau" in the xorg.conf file and restart X? I know if it won't start X I can boot to rescue mode and re-edit xorg.conf, but I'd rather ask first and do it the right way than have to repair a broken system.
I connected an external 22" monitor to my new linux netbook and now I am trying to improve the display clarity. By shifting the "clock" monitor bar to 100 ,the letters were less faded but edges of my screen were lost (by zooming in). Can I fix that through Linux?
I just got Ubuntu 10.04 installed and I seem to be having a problem as many others with the sound. because a laptop with no sound tends to be a wee bit boring
