Ubuntu :: Wrong Resolution With ATI Radeon 5450?
Mar 20, 2011
i got a dell computer running ubuntu. it is equipped with an ATI radeon 5450, using a dell IN2010 1600x900 screen. when i installed ubuntu, the resolution was just fine. then i installed the ATI driver, and from that moment on, i have that strange behaviour: when i start ubuntu, the resolution seems set to 1440x900, but stretched to wide-screen mode, so the font is somehow blurry. when i turn the monitor off and then on again, everything is just fine.i have catalyst control center installed, and the resolution is set to 1600x900, but i still have the problem that i described.

Just purchased and installed an ATI Radeon HD 5450 graphics card and installed the proprietary drivers via System > Administration > Hardware Drivers. After rebooting the machine X would not load so I restarted into recovery and removed my xorg.conf. At this point I could restart normally and the machine would let me into X. I went to System > Preferences > ATI Catalyst Control Center to try and configure the card.
I receive the following message:
There was a problem initializing Catalyst Control Center Linux edition. It could be caused by the following. No ATI graphics driver is installed, or the ATI Driver is not functioning properly. Please install the ATI driver appropriate for your ATI hardware, or configure using aticonfig.
So, I did just that, I restored my backup xorg.conf (configured for nvidia card) and executed 'sudo aticonfig --initial', it made the proper changes and additions to the configuration file and this is what it looks like [view xorg.conf]. I then restarted the machine and X still refuses to begin [view Xorg.0.log]. Again, I went in removed the xorg.conf file and the machine will load normally. I tried running fglrxinfo to try and see if the card was properly installed and it just threw a segmentation fault.

After installation of the new hardware I activated the ATI closed source driver. There is an issue with the screens
1st screen, via DVI: I cannot change to the native screen resolution
2nd screen, via VGA: The background of any window is not drawn.
Means: I can see lots of parts of other windows after moving or closing them.
Therefore I was searching for an alternative and found the hint to uninstall the ATI driver and use the open source one. After uninstall and reboot (requested by a parallel system update), some boot messages I have no screen output anymore. Means: two black screens. These are going into sleep mode after a few seconds. How can I get a running system again? Optimal would be, that I have full support for both screens. Same happens in failsave mode.
System environment:
Ubuntu 10.04
AMD Athlon 64 X2 3800+, 4G RAM, motherboard ALiveNF6G-DVI (internal graphic deactivated), ATI Radeon HD 5450

Few week back I downloaded this driver ati-driver-installer-10-12-x86.x86_64 from AMD/ATI. Everything when ok then I decided to reboot f@@@@K the system up kept rebooting all the time so I did a fresh install again and downloaded the Driver again but this time I need QA. Is this driver will solve my issue of Accelerated 3D graphics is not available? Will this mess everything up again? If so how can I recover without having to do a fresh install?

Installed Ubuntu 10.10 on fresh HP dm4-1050so laptop and encountered problems, this is one of them. Noticed that ATI card is heating heavely with default installation and I would like disable it and switch to use Intel's GMA. Also tested ATI proprietary fglrx driver through Administration->Additional Drivers, after booting got empty screen so I switched back. Afterwards read from documentation that 5450 is not supported, so no wonder. So what is the simplest way of disabling ATI and using only Intel's gma? Here's what I got with lspci -v:
Code:
00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 02) (prog-if 00 [VGA controller])
Subsystem: Hewlett-Packard Company Device 1469
Flags: bus master, fast devsel, latency 0, IRQ 45
Memory at c0000000 (64-bit, non-prefetchable) [size=4M]

I recently installed ubuntu 10.10 on HTPC, after having a few RAM and SATA issues everything seems to be working fine, The audio (using HDMI) does not work. Have PC connected using HDMI for video (and I am hoping for audio too, this card is made for this and it has been tested with other OS) however the audio does not work, although in the audio preferences it shows to be using the correct hardware. Testing for sound under sound preferences does not play anything, acts as it it was, but no sound, no error messages either. I went ahead and installed ATIs proprietary drivers in hopes that it would make the audio work, but not luck so far.

I recently bought 1GB video card of 'xfx radeon hd 5450'. It came with cd for drivers of windows.
I installed fglrx. Still in ubuntu 10.10 (lucid) I ran: lspci -v | grep -i prefetchable
which shows 256M which is video memory of my ASUS motherboard.

After having problems with an onboard graphics chipset I've just installed an ATI Radeon 128Mb 9000 Pro AGP graphics card into my old computer... The problem is that I can't get it to use 1440x900 resolution that my LG L194WT (Ubuntu won't detect it) requires and the highest I can select is 1360x768 and that looks all wrong
lspci gives:
Code:
01:00.0 VGA compatible controller: ATI Technologies Inc Radeon RV250 If [Radeon 9000] (rev 01)
01:00.1 Display controller: ATI Technologies Inc Radeon RV250 [Radeon 9000] (Secondary) (rev 01)
And /var/log/Xorg.0.log gives:
Code:
X.Org X Server 1.7.6
Release Date: 2010-03-17
X Protocol Version 11, Revision 0
[code]....

Sometimes, randomly, when turning on my Ubuntu laptop (HP 6730b, Ubuntu 10.04) I get a wrong monitor setting (much lower resolution than normal) and it is not possible to set it correctly because the menu buttons are wrongly placed and some are not present (probably there is not enough room for them) I have no other way than to restart the system to get the right resolution. Can someone tell me this inexplicable (to me) behaviour? Of course I didn't change anything in monitor settings...

My Acer AspireOne netbook has a native resolution of 1024x600. Most times I start up, the image is 800x480 against the left edge, black bar on the right side, and a repeated image at the bottom. (I can attach a picture if needed.)I've been seeing this problem since Ubuntu 9.10, but it's more common recently with 10.10. If I keep shutting down and powering back on, eventually it will come up in 1024x600 as I desire. If that happens, then I avoid shutting down and only use Suspend instead. However, anytime I need to reboot (for updates, etc.) the 800x480 comes back.
The Acer logo / BIOS splash screen is also in 800x480, but I only see it switch back to 1024x600 after Ubuntu loads and is shut down. (Repeatedly clicking on/off/on/off never results in the resolution changing to 1024x600.) So, I'm still suspicious that Ubuntu is causing this (no hardware). WinXP used to be on this machine, and the problem was never seen.I don't think any proprietary drivers are needed (but I am still a Ubuntu noob.) When the problem is occurring, I see this result for xrandr:
Code:
swope@netbook:~$ xrandr
Screen 0: minimum 320 x 200, current 800 x 480, maximum 4096 x 4096
VGA1 disconnected (normal left inverted right x axis y axis)[code]....
I haven't been able to find xorg.conf ... but I've read that recent versions of Ubuntu create the content dynamically.Not sure what other details I should be including, at the risk of making this post too long.

every since I installed natty in march my refresh rate has been wrong this makes it where I can not see the boot screen, this was not a big problem until I installed the developmental version of ubuntu to test for bugs and I can not see the boot screen, I went to the page that tells how to change the rate but I get this error when I ran xrandr Failed to get size of gamma for output default. This showing my monitor as default it does not show a name, I manually set it up in x server and it shows the correct rate and the correct monitor, but not in monitor preferences.

I have on old Thinkpad T42 with the Mobility Radeon 7500 graphics chip. It used to work like a charm with the open source radeon driver, until KMS came along. It had no problems except for fullscreen being always black. I thought this is because I have an old card, and used 'nomodeset' in the kernel line, which strangely cranked up the memory usage and made the system choppier, but I managed. Today I was testing the use of an external monitor at home, and found out not only that it only works properly with KMS enabled, but fullscreen games work like a charm (e.g. DOSBox, which I use a lot).
After experimenting a bit, I found out that on the internal display (LCD), 640x480 produces a black screen, while others work as expected. so i set dosbox to use 800x600 as the fullscreen resolution, and it works. The problem is that there are a lot of games (and apps) that I use which provide no configuration options to set the resolution, so I end up with a black screen (when I'm using the internal display, of course). Bottom line: I'm not asking for anyone to fix my problems from a distance, basically blindfolded.

I've got a HD screen: 1920x1080p. Grub (1.98 ) has the resolution: 800x600 and Plymouth also. It is irritating me that plymouth shows a very ugly purple splash screen in a very low resolution (800x600). How can I fix that? I've got an ATI Radeon HD 4670, and use the drivers from ATI...

I installed Ubuntu 11.04 about a week ago and everything has been fine except that Ubuntu thinks my monitor has a resolution of 1024x768, while the actual resolution is 1366x768. I can't set a higher resolution through the visual interface (my monitor is detected as "unknown") Are there commands I can issue through the terminal to sort this out?

I have no other gripes but one minor problem; After the boot, the KDE4 desktop starts with a resolution of 1152x864 instead of 1280x1024 selected at display settings. Strangely, it seems to activate the correct resolution instantly when I enter the display settings menu that shows the intended resolution (no need to apply anything). Going to the settings menu is a bit bothersome after every boot.

I've just upgraded from Debian Lenny to Squeeze. It didn't go as smoothly as I had hoped, one of the casualties being the proprietary nvidia driver I had previously installed. So I fixed that using the 'Debian way' rather than NVIDIA's installer, and that is now all fine. So far so good. However, when I boot up, pre starting X, my screen is a much lower resolution than it used to be (640x480, I think). Really chunky and ugly as it runs through the start up scripts. I assume that somewhere early in the startup scripts the nvidia driver is being loaded and set to a low resolution. Can someone advise me where this might be, and what to look for? Am I on the right track? I stress that this is before X is started. Once X has started the screen resolution is as I want.

I have a machine with an ATI Radeon 7000/VE graphic card and I can not get the screen resolution I need. This is running on redhat enterprise 4 OS (32bit). My monitor is a 1600x1280 but I can not get anything better than 1024x768. I did set the desired resolution in the xorg file. I guess this would rather be a driver issue? I am running with radeon driver at the moment. I tried to get the fglrx from ATI but they do not seem to give any linux support for this card.

setting a resolution that my monitor can't handle, and now I can't figure out how to get back to a setting that my monitor can handle. When I first made the bad setting, the screen went black except for an "Out of Range" message in the middle, and wouldn't let me see anything to put it back. I ended up going to a text screen with a <Ctrl-Alt-F1>, logging in as root, and rebooting. Now, I can use all of my other user IDs (root, KDE test, "email only," etc.) just fine, but if I log in to the one with the bad res. setting, it just blacks the screen and I have to reboot again. The xorg.conf file doesn't even have any options for setting resolutions any more, so there's no way to explicitly disallow the one I set, and "deleting" (renaming) xorg.conf didn't help.

on an older computer. I get as far as the screen that asks if I want to try or install and then I get a message saying the screen resolution is wrong and I need to reset. I even disabled the hard drive in bios and still get this message. computer was built to run xp and had ubuntu on it before. I tried to upgrade the nvidia driver and broke it.

I have a desktop with nvidia 9300 connected to a 37" LG hdtv lcd with a VGA analog cable. I'm using this machine as a media center. Up until now it had a windows XP and (besides the fact that it had windows) it work with the correct resolution - 1920x1080. I've installed Ubuntu (the latest available) after to many crashes during hd movies...
I installed the nvidia restricted drivers (the display is plain black otherwise) and my tv is being recognized as a CRT monitor. Guess it's because I'm using the vga connector instead of the dvi one. The problem is that the highest resolution it let me choose is 1024x768. I tried to mess around with the xorg.conf but i discovered it doesn't exist.

I have installed Debian Lenny with LXDE on a Dual USB 500Mhz iBook g3 the login screen appears displaying the screen using "800x600" pixels with the screen resolution at "1024x768" - so the login screen fills 2/3 of the LCD with black space to the right and the image repeating itself in the bottom 1/3 of the screen The "System Tools" > "Monitors Settings" only list one setting size of "800x600" and "Auto" After trying to search for answers I have tried editing the /etc/X11/xorg.conf file (after stopping gdm and rebooting afterwards)
# ... after these lines
Section "Screen"
Identifier "Default Screen"
[code]...
But nothing changes.
I have also tried [ dpkg-reconfigure xserver-xorg ] but there is no prompt for resolution

I'm running OpenSuSE 11.2 with an Nvidia GeForce 8200 on board graphics card and am running the drivers installed from the file NVIDIA-Linux-x86-190.53-pkg1.run which I obtained from the Nvidia web site. I also have this vga directive on the kernel line in /boot/grub/menu.lst vga=0x346 Yet, sometimes when the system starts up it will go into 640x480 mode instead of 1680x1050. If I shutdown and restart a few times it will eventually come up in the proper resolution.

I have problem with resolution (@gnom desktop). In Yast --> videocard & monitor is all right. There is correct resolution 1366x768 (WXGA). Also the videocard ( I don't have really one, only chipset "Intel Mobile GM45" ) is correct recognized. But Monitor isn't recognized, and I don't know which one I have (It's notebook from acer).
Nevertheless if I go direct in monitor preferences (at the bottom the monitor with a ruler symbol) the resolution is set to 800x600 and I can only change to 640x480. The monitor is as 15" recognized (I have 15.4", even a bit more broadly - 1366x768) and now I don't know what to do. All symbols, all programs, everything is huge! How is it possible to configure the correct one resolution?

I am new to Linux (Ubuntu 10.4 LTS on a Thinkpad T40), now just two days, and had everything working nicely. But since I wanted a better higher resolution I tried to set the monitor resolution to a higher value. After selecting a higher resolution first the screen went black and now it has a white background and is steady but has flickering areas. The system is still working. How can I go back to the resolution that was working?

I just installed drivers for this nVidia GPU from the website. Now, whenever I boot, the screen resolution goes to 1024x768 instead of 1280x800 like I want it to. I have to change the screen resolution every time I boot into Ubuntu.

On my Acer laptop wit ATI Xpress 1100 I have a native resolution of 1280 x 800, and Linux Mint 8 (of the Ubuntu family) offers that resolution without a problem. However, a few days ago I connected my laptop to my TV, and since then the correct resolution setting has been LOST. It doesn't appear anymore in the Display settings and so I had to choose a lesser resolution - I am now looking at a less sharp screen! How can I delete it? I hope that I don't need to reinstall...
