Fedora :: AMD Ontario And Graphics Performance
May 8, 2011
Recently I noticed there are on sale, from several manufacturers, some interesting and inexpensive laptops equipped with AMD's new Ontario C50 processor which for one thing seems to use little power (like the Atom), and the other and more interesting is the fact that it has the graphics embedded.
I am curious if someone here owns one of said laptops and can comment about the performance/compatibility of this Ontario chip, because some of these laptops are such good deals that I am seriously considering at least recommending them. Obviously if I purchase one of those I'd install Fedora on in. Two things puzzle me: is performance very far apart from that of a netbook, and second, how do the graphics perform? Do they use the Catalyst driver as well?

I just did (another) fresh install of FC13. On the last install I attempted to install the nvidia proprietary drivers (tried every guide I could find). When I installed the proprietary drivers, I could no longer boot. It would hang at the end tri-color progress bar. I could ALT+F2 to get to tty2, and deleting the xorg.conf file and init 5 would get me back to the Gnome login. I continued trying other methods, getting such results as a black screen with no way to access tty. I tried using the rescue function from the DVD, but this time I couldn't fix the problem by deleting xorg.conf and executing init 5.
After failing in everything I tried for the proprietary driver, I decided I'd give the new nouveau a shot. Every time I fresh install FC13, the graphics performance is TERRIBLE. Moving a window around or scrolling in Firefox is painfully choppy and borders on unusable. I tried 'yum install mesa-dri-drivers-experimental' but after rebooting the performance was still beyond crappy.
I can get proprietary drivers working in Debian Lenny without breaking a sweat, but I prefer Fedora as a whole by far.

I just wiped my hp 6730b laptop after having done something that killed my previous fedora 14 install but now the graphics are all choppy. The previous install was a 12 to 14 upgrade that ran fine after only minor tinkering to straighten out some leftover stuff. The new one is a net-install of the 64bit version. But now X is all choppy and 2 processes seem to be using some cpu when X starts up: 'kondemand' and 'migration'. Eventually the screen will start to flicker but it'll keep running 'normally'. I am guessing that it is somehow related to the intel driver seeing how 3d (compiz) is not working either. So far all I changed is the default runlevel to 3 but it makes no difference if its in 5. I tried making a new config with X -config but then X does not start at all. system-config-display has been removed so I cant try fiddling with that either.
Hopefully all the required / useful info:
(there is no xorg.conf)

I was using centos for my business applications and now I am trying to work only with opensuse and install my other oprerating systems in it. I was always using vmware , but I decided to try another virtualization technologies other than vmware for testing , I searched the internet and found many other like virtualbox , kvm , xen. I concluded from my search that xen and kvm will be the faster type , I decided to test them, I choose xen, it is better than kvm. I installed opensuse 11.4 and installed xen hypervisor deployed two VMs windows xp and centos 4.8 , they are runing quite good but I have some questions:
1 : Isn't there anyway to improve graphics performance in xen guest , or change the video card memory or type ?
2 : Isn't there any way to copy and paste between the host and guest ?
3 : Isn't there any free application like vmware tools or virtualbox guest tools for xen ?
4 : I use these VMs to install some applications for my geophysics work which requires good graphic performance in the vm , also I don't them to be sluggish sometimes , which is better for that vmware or xen ?

I have an 11.2 laptop and thought it was time to upgrade to 11.4. I downloaded the 11.4 X86-64 live cd and thought that I would check how it ran on my 11.3 desktop. This is a core i5 760 with an Nvidia GT240 graphics card and 4GB of DDR3 ram. The 11.4 live system shows the nouveau driver. The graphics performance is terrible. In particular windows are very very slow to resize and often don't resize properly. There are also some artifacts in some graphics. I eventually downloaded Flash which did seem to work moderately well, especially in full screen mode. The screen resolution is 1920x1080. I have never seen a windowing system work so slowly
While I always use the Nvidia proprietary driver, I don't know how I can test it via a live CD. The Nvidia driver in the repository is the 270 version and I think that I have seen reports of severe problems with the 270 version so that needs to be tested too. I always install the nvidia driver the really easy way via yast
Has anyone any idea why the KDE Live graphics are so slow? I will not go anywhere near 11.4 unless the graphics system is very much faster. Is there any way to test the nvidia proprietary graphics driver without installing 11.4?

If I wanted to step away from the non-free world and constant battles between nvidia and amd, where would I go? I am considering updating my graphics card and would prefer to make the use of open source drivers and not bother with the proprietary ones but I still want a card that's going to be reliable and give good 3d performance to run unity and some 3d games.

I've recently been experimenting with glxgears, but found people saying this is not an ideal benchmark tool as there are many variants; for example resizing the window affects the FPS tremendously.
I'm interested in testing the difference between using the proprietary ATI driver and the open source driver and also the performance under various distributions.
What's the best software to benchmark graphics cards?

I have an ATI RADEON 7000 (taken from lspci) 64 MB graphics card. My computer has a 700 MHz Celeron CPU and 650 MB RAM with Ubuntu 10.04. Anything graphical is slow. I cannot even play basic games like SuperTux. I think it is a graphics driver problem. Will this card ever work well with Linux, what do I need to do?

I have installed several different distro's over the last coupled of weeks and have finally as intended come back to 11.4. Last time I installed it my pc was fitted with an older nvidia card and I installed a newer 200 series and got it to work with X11 using the nvidia driver. This time I did the install with the new card in and things haven't gone the same way. I have finished up with the os drivers on my system, nouveau and "swrast (No 3D Acceleration) (7.10)". Performance wise it's way way behind the nvidia driver.
Glxgears for instance runs at under 1/2 the speed even at a lower resolution. I suppose I could still configure to suite my monitor but given that difference in performance would you? I have done what I can easily do with repositories but no signs of nvidia drivers. I can download one as I did last time but from what I have read previously the above drivers may mean that I have to recompile the kernel. A simpler solution might be to re install with my old card in. Can't say I'm too keen on either option. Some distro or the other had a driver helper and installed the nvidia one perfectly.

I am running kubuntu 9.10 on a dell inspiron 14 with an intel GM45 graphics card. When I run 3d games like Nexuiz, openarena and tremulous I get really random performance. Sometimes things are totally playable with somewhere between 50-80 fps and other times I get maybe 4 fps and everything takes forever to load. These effects persists between logouts, X restarts and reboots! I get no errors when I run things in console either.I never really play games much but when something doesn't work...

i have an ati radeon x1550 (pretty old, i know) graphics card which worked perfectly under windows 7. i recently read that ati appears to have dropped support for this card installed on recent ubuntu distributions (i'm using ubuntu 10.10 + kde 4.6.1) the thing is, when i'm watching something on videos or playing a movie through vlc, the image looks jittery (random horizontal lines that break the image, it's pretty subtle but it's there...) i'm new to ubuntu (switched from windows 7 a couple of months ago) and what i'm looking for is one of two:
-either a solution to my drivers problem so i can use this card with full 2d and 3d support (like i used to in windows) or, a recommendation of which graphic card i should switch to (my motherboard has a 'pci express x16' slot). i've searched countless forums and sites but i can't reach a final conclusion: am i supposed to have good 2d and 3d acceleration with this card (with the right drivers installed)?
if the answer is 'no', then i'd like to know what i should buy. for what i've read, apparently i should stay away from ati and intel and look for nvidia. i'm not a gamer so i really don't need an incredible 3d acceleration (although some would be nice, just in case) what i really need is for my system to be snappy (i work with my computer) and most of all good support for multimedia apps (i would like to be able to use xbmc smoothly for instance) i'd like to know which is the cheapest graphics card that i can get that will meet my needs (the ones i just listed above)

I have been trying to enable compiz on my fedora 14, but when i enable the desktop effects the graphics just crashes and fedora freezes. When i type lspci -nnk | grep VGA for the graphics card i get:
I made alot of research on how to get Intel graphics work on Fedora, but couldnt find any solution
Same problem I had with Fedora Core 12 and 13.

I just wanted to know if having my laptop set to ondemand, will this affect performance in any way? I realize it increases the clock speed to performance when the CPU is under load, but does the time it take to go from ondemand to performance affect speed? Will there be any noticeable difference between the two setups? I have a dual core intel at 2.2GHz when in performance. When ondemand is set with no load it downclocks to 800Mhz.

I'm noticing that the performance for FreeNX Server under Fedora Core 14 is really bad. The screen refreshing is painfully slow. I'm thinking maybe the issue is related to the use of opengl in the X driver? how I can disable opengl entirely, so that the X server is only using 2d rendering?

After being forced to rebuild my computer (failed drive) I finally got current and installed F11 (was using F9). I was watching GKrellm last night and noticed something odd. The CPU frequency on my processor (Phenom 9600) was scaled to the slower speed and was rarely being pushed to full speed.
I verified that cpuspeed was in ondemand mode and ran some processor intense tasks (huge image loads, large file cats, large yum installs, etc...). Only when I was able to sustain near 100% load would the system throttle to the full clock speed. It would then drop back to the slower speed very quickly even though the process was still running. As a rough benchmark, I ran these tasks again in performance mode to see what impact this was having. Most of these tasks were taking as much as 40-50% longer to complete in ondemand mode.
Digging further, I found that the default up_threshold in F11 is set to 95%!! This is verified by cating /sys/devices/system/cpu/cpu0/cpufreq/ondemand/up_threshold. This means that the system would not throttle to full speed unless a 95% load was sustained for multiple samples (36 miliseconds each by default).
I overrode these settings in /etc/sysconfig/cpuspeed. I change up_threshold to 60 and down_threshold to 30. I am at work right now, so I can't benchmark this change until tonight. I guess I could have just set it to performance mode and left it, but I'd rather save the power when the machine is idle.
Does anyone have any thoughts on why 95% is the default and if there is any problem/benefit to changing this to a much lower value? It seems that anyone with a CPU running SpeedStep or CoolnQuiet would suffer the same severe performance impacts I saw with the default values.

I av just started out with fedora (fedora 15 64bit) and everything is dandy except i get less than an hour of battery life on my laptop. I used to get around 2 and half hours on ubuntu natty. could someone help me figure out whats going on?All hardware has been working well and i havent installed any proprietary drivers except the WLAN broadcom driver.

I have a Dell Inspiron 1525 laptop with a X3100 on board. The problem is the performance doesn't really fit my expectations. Compiz works fairly OK, but TuxRacer runs at 25 FPS, Glest runs just terribly slow and there is quite noticeable tearing in videos (MPlayer and Totem). Not to mention 400-600 FPS in glxgears.So far I have only tampered with Xorg (see below, changes marked red).
Code:
Section "ServerLayout"
Identifier "X.org Configured"

I have fedora 12 and since I started using firefox I noticed that it performs very slow. Slow when opening, when displaying information etc..I thought that there was something wrong with my wireless device but I installed opera and it works very fast. The strange thing is that before that I installed google chrome and also worked very slow for me.

I am trying to set up linphone for testing voip performance. Essentially I am a beginner with linux. I picked Fedora based on the recommendation of a friend. I am running Fedora 12 and I need to get linphone up and running with a working registrar. I have no idea what to do so I turned to hours of research which yielded little results but I did thing to try using partysip. I would like to know if this is a wise choice and if it is what do I do to set it up?

My computer is running really slow after a power outage. It was fine, then the power went out. Now it's *unabably* slow. The OS takes a long time to load, the simple calculator takes a few minutes to show up, Firefox doesn't even load at all before I give up. And it won't shut down normally. I have to use the power button.
So did the power outage fry somthing on my PC. Do I have ot replace RAM or the processor? Or is it a software issue? Do I have to do something as drastic as a reimage?

Now that I think about it, I'm not sure if its a problem with sdlmame or the Gnome front end.Is anyone successfully running MAME under FC14? If so, what did you have to do? Did you have a similar experience to mine? How did you correct it?

I need evaluate the ext3 file system performance; i need define:
- services provided
- parameters and
- the performance with different parameter values; for example, changin the value of the "data" parameter (journal, ordered, writeback).
I do not know what services ext3 provides. Well, i know intuitively that it provides services to read, write and erase files. But, there are anything more?. Where can i find the API?. Is the ext3 file system POSIX compliant?

It's been a while now I've been experiencing an annoying issue with F12. The thing is that after the machine resumes from suspend (which is otherwise a perfect procedure), video performance (and sometimes audio, through Rhythmbox) reduces and videos play sluggishly. Rebooting the system fixes the issue.
Is there a solution for this behavior (other than rebooting)? Here are the details of my system: F12 x86_64 on an ATI graphics powered machine (Radeon HD3200) which obviously uses the free drivers mesa-drivers-dri-experimental which, otherwise work perfect on this hardware.

Linux OS Version/Release: Red Hat Enterprise Linux Server release 5.5 (Tikanga) Linux <hostname> 2.6.18-194.8.1.el5 #1 SMP Wed Jun 23 10:52:51 EDT 2010 x86_64 x86_64 x86_64 GNU/Linux I have a server that hosts 30+ Oracle databases. Each database has its own set of scripts that shuts down the database and start the database. Things has been working "smoothly" in the last couple of months until this week.
My log in most cases shows errors like the ones below:cannot fork [Resource temporarily unavailable] Connection reset by peer I am 100% sure that the scripts are not at fault since it has been working with no errors for months. I want to monitor the server for what resource or configurations I have to tweak to get around this problem if possible, am I exceeding my ulimit settings running out of process,out of memory/swap space etc?
I wish I could stay up 24x7 to monitor to monitor the server but I can't. Can anyone please advise if there is any monitoring script available somewhere that I can put in cron to temporarily monitor the server for resource issues, for example memory used/left, swap space used/left, ulimit-num-process used/left, nofiles used/left etc.

My wireless was connecting fine, but it was impossible to browse with. So, after searching around for a while I found a thread where it said to enter this and reboot.
#echo "net.ipv4.tcp_moderate_rcvbuf=0" >> /etc/sysctl.conf
#echo "net.ipv4.tcp_default_win_scale=0" >> /etc/sysctl.conf
But after entering that and re booting, now I cant even connect to the wireless. It says connecting but times out.

On F13 i386 inside Virtualbox. Host is a Win7 x64 box.
This may just be more idle curiosity than anything else since the server still works. . . but it's really bothering me because I can't explain it.
My (limited) understanding is that the devel files are just the source files and shouldn't actually affect peformance.
Yet, prior to installing httpd-devel (and its dependencies), /etc/init.d/httpd restart takes about 2 seconds total. After installing httpd-devel, the "stopping" phase of the httpd restart take 5-7 seconds (which seems really long when you're just sitting there waiting on it.
yum install httpd-devel also installs the following for dependencies:
db4-cxx
db4-devel
cyrus-sasl-devel
apr-devel
apr-util-devel
openldap-devel
expat-devel
All but one of those are devel files as well. And here's the real kicker: Uninstalling them through YUM doesn't put things back to normal (even after reboot).
I'm no linux expert. But I wouldn't think installing devel files would have this effect or any effect like this since they're just source code files (?). Can anyone explain what's happening or give me tips on how I can watch the apache process stop and see what's hanging it up?

I have a dual boot on a netbook with windows and fedora13. When I am on my fedora boot and I try to watch streaming video it comes through in waves or not at all. I do not have the same problems on the alternate boot. There are other performance comparisons where the windows boot runs smoother and faster. Is there any work I can do in order to optimise my fedora boot in this capacity?
