Hi, what are opensuse 12.1 hardware requirements?
Thanks.
You mean system req
This is 11.4
Hardware requirements - openSUSE
12.1 will be the same I’m sure
Be aware that 12.1 is beta at the moment
in my signature you can see my laptop config. the config is not bad but opensuse 11.4 is slow in my laptop. for example firefox 7 in opensuse 11.4 is slow in scrolling pages up and down.
do you know the reason?
What video driver are you using with your GForce 8400 GS ?
In case you do not know how to determine this …
Note the ‘my computer’ icon in KDE does not always report the correct driver. What is output of the command:
/sbin/lspci -nnk | grep VGA -A2
If you are using the proprietary nvidia graphic driver, that should show it.
Else, open the file /var/log/Xorg.0.log and copy the contents and paste the contents to SUSE Paste and press contribute and copy the website/URL where that paste is now located and post the web/site URL here. We can look at it and tell you what driver is in use. Do NOT post the content of Xorg.0.log here.
ok, i should say i updated video driver to proprietary nvidia graphic driver, and i feel before updating to nvidia driver, my opensuse was faster.
Unless there is a problem with your proprietary nvidia install, then the proprietary nvidia driver should be faster than both the nouveau and the nv video drivers.
Some questions:
-
you say you updated to the proprietary video driver. How did you do that ? repository method ? the manual way (called in the old days the ‘hardway that is not hard’) ?
-
what version of the proprietary video driver are you using ? Not just what rpm version (if using the repository method to install) but what nvidia proprietary video driver version ? Note the most current proprietary nvidia video drivers versions are listed here: Current NVIDIA Linux graphics driver releases - nV News Forums
-
what have you checked to CONFIRM the proprietary driver was actually properly installed ? Did you follow my suggestions in post # 5 ?
-
if you believe the previous unknown driver (unknown because it was not specified by you in your post and we are left to speculate as to what that might be) driver was faster than the proprietary video driver, did you try rolling back to this unknown video driver ??? to see if your assertion was accurate or subjective and inaccurate ?
my answers are:
-
i do both method, one time hardway … and another time with repository update (because in hardway… my system was slow, so i tried to update using repository to solve the problem) but both of them had same resaults.
-
know i cannot access my laptop to give you the exact version but i think it was 275.28 or maybe 280.13.
-
no i do not follow your suggestion in post # 5 because i cannot access my laptop know. but when i clicked in “My Computer” in opensuse desktop, it showed me Nvidia as graphic driver.
-
my previous driver was pre installed graphic driver in opensuse 11.4 called nouveau (i think), and i did not know how to roleback to that.
As I noted, this method is NOT reliable and the method I suggested in post#5 is superior and more accurate.
If you installed the manual method (in the past called 'the hardway (that is not hard) ’ ) and if you open the NVIDIA-Linux-x86_64-275.28.run with a text editor, you will find you can actually read some of !! You will see the option :
echo " --uninstall"
echo " Uninstall the currently installed NVIDIA driver."
That tells you how to uninstall the driver.
Ergo, after having installed the manual method you simply type with root permissions:
sh NVIDIA-Linux-x86_64-275.28.run --uninstall
NOTE that is NOT the case for the repository method. In the repository method you need to uninstall the rpms that you installed (I assume - I have never installed the proprietary nvidia driver using the repository method).
Note if you blacklisted the nouveau driver as part of this in /etc/modprobe.d/50-blacklist.conf, you need to remove the blacklisting. And if in YaST > system > /etc/sysconfig Editor you set under kernel NO_KMS_IN_INITRD=yes then you need to set it back to ‘no’.
The above assumes you were using the ‘nouveau’ driver before. Reading your post it reads that you are not too certain. 
I recommend you also find out what proprietary nvidia graphic driver version you are using and check to see if it was the latest or an older version and if there were any associated issues.
Also, when you encounter such behaviour, it would be useful for you to check to see if any other processes are running. We can’t do that as we are not on the PC. Have ‘top’ running (in a terminal (bash shell) window session), and then scroll back and forth in Firefox to reproduce the behaviour and take note if any process is consuming a lot of CPU.
Note a Gforce 8400 GS is a very slow graphic hardware device. Do you have special desktop effects enabled ? How is the firefox scrolling performance if you turn that off ?
OK, about the correct installation of nvidia driver i want to add that after installation of nvidia driver, each time i boot opensuse it shows me nvidia logo in booting period for a while. is this shows that installation was successful?
you said: “Note a Gforce 8400 GS is a very slow graphic hardware device.” but i want to add my laptop has 2 OS, opensuse and windows vista, i do not this problem in vista (and maybe you know that windows vista is a very heavy OS) i even play games in vista and do not have such a problem in that, but in opensuse scrolling up and down a webpage or an office document is very slow and is a kind of problem!
about effects i should add that i do not add any additional effect to original (predefined) effects of opensuse 11.4. two or more times i disabled the effects but i face with some problems such as hiding and appearing window borders frequently and … so i turned back to effects enabled.

there are lots of possible problems causing slow scrolling in firefox:
faulty java scripts on the web site is one…
depending on the site visited it might be network disruptions–i know a
combo of java scripts and network traffic sometimes makes scrolling at
facebook exceedingly slow and jerky…sometimes it just stops and
nothing happens…but, if i open a new tab at a site i know has no java
script it scrolls smooth as a baby’s bottom–so, it is not always
correct to point the blame at either firefox or SUSE…
on the other hand, if scrolling is always slow then you have a
problem, how does this page scroll:

You need to decide what is important to you. Effects or performance?
Reference the nVidia splash screen, … all that says at that point in the boot process the splash screen was loading. Its 99% likely that then the proprietary driver loaded, but why leave this to chance.
I have to say if you can not access this laptop to debug, then you are likely wasting the time of both of us. You need access to sort this.
Don’t forget to run ‘top’ when the slow down problems occur, so as to read what is causing the CPU load (if any). Without that I am only offerning up pure speculation in an effort to help, and I have to say that is not pleasant to be forced to speculate when better information can be possible. So please run ‘top’ as suggested.
I had a user on another thread compare about poor performance and it turns out they had inconsistent kernel versions installed. So please also provide output of:
rpm -qa '*kernel*'
and note that is only speculation because the information that might be useful from running ‘top’ has not yet been provided.
OK man, i am in work and my laptop is in home!!! i can access it some hours later not know! OK?!
ok, i do your recomendation in post # 5 and here is the resault:
linux-4xk6:~ # /sbin/lspci -nnk | grep VGA -A2
01:00.0 VGA compatible controller [0300]: nVidia Corporation G86 [GeForce 8400M GS] [10de:0427] (rev a1)
Subsystem: Hewlett-Packard Company Device [103c:30cd]
Kernel driver in use: nvidia
also the resault of another command is:
linux-4xk6:~ # rpm -qa '*kernel*'
kernel-desktop-2.6.37.6-0.7.1.i586
kernel-firmware-2.6.38-1.2.1.noarch
kerneloops-0.12-41.1.i586
That confirms the nvida driver. How about the /var/log/Xorg.0.log that I asked a link to (from SUSE Paste). Any unusual errors there ?
How about top ?
And the output of:
rpm -qa '*kernel*'
ok, i do your recomendation in post # 5 and here is the resault:

OK, that was a surprise. I recall you stated this:
- i do both method, one time hardway … and another time with repository update (because in hardway… my system was slow, so i tried to update using repository to solve the problem) but both of them had same resaults.
For the ‘hardway’ to work, one needs kernel-source installed (of same version as your kernel) and also possibly kernel-syms. Did you install that package and then remove it later? If you did not, then the hardway would not have worked and the behaviour observed would not have been the proprietary nvidia driver but some other driver.
Also, I note you have the updated 2.6.37.6 kernel. Did you update your driver after updating your kernel from the original 2.6.37.1 to the current 2.6.37.6 ?
