Screen output jerky, laggy, studdering with AMD/ATI driver

Postby GartenEden on Mon Jun 24, 2013 1:40 pm

Hi folks!

As the subject already told you: My entire output (not only Youtube/Flash) is very slow. One can notice it even while scrolling in browsers, Nautilus, switching workspaces etc.

There aren't any fglrx drivers for my RV620 anymore so I have to stick with the open radeon driver. That is what I did using Ubuntu 12.04 and there was everything fluid and nice. So I know that it is possible to have a good graphics experience with Linux and my hardware.

I already tried a kernel update and am running LMDE with Kernel 3.9-7.dmz.1-liquorix-amd64 and an up-to-date graphics stack.

Looking forward for any ideas! Thanks!
Eddie

Code: Select all
drm
radeon modeset=1
I'm not really sure, but adding these lines on /etc/initramfs-tools/modules then update the initramfs using 'sudo update-initramfs -u' seems makes my gpu performance better. there are also several report about adding 'xforcevesa' to grub parameter which makes graphic better.

Sadly, it made no difference to me. I tried both :(

Since your RV620, AMD Radeon HD3450 (256MB PCI-Express x16 RV620), v.8.581 XP32, A04 is group as legacy, you can consider these steps:

1. Backup / clone your partition OS to external USB drive, so that in case during testing installation, if something happen you can restore from USB drive

2. Suggest to test install on Debian kernel. Not the liquorix.

If you must use liquorix kernel, then, go to try using smxi/sgfxi to install and see what it said.

3. Read this post

HOW TO Install fglrx-legacy for HD 2000-4000 chips in Wheezy
http://forums.debian.net/viewtopic.php?f=5&t=103918

4. add Debian sid repos

5. purge all stuff related to old fglrx installation

6. install fglrx-legacy

7. reboot to check, if working.. remove Debian sid repos or comment it out of sources.list

Once again, please backup/clone, so that you can restore to original OS if some weird thing happens

Thank you for your detailed answer, wayne128.
I hope it doesn't sound too demanding but I'm just wondering why the old radeon driver on Ubuntu worked that fine for me and the LMDE graphics do not. I would really prefer using the free driver over the proprietary fglrx.

If you prefer to use Radeon, then , there is no need to bother installing fglrx.

read mint14 release note http://linuxmint.com/rel_nadia.php

you would know legacy driver does not work with new xorg driver.

i am not sure what is LMDE's xorg version, but most likely if you have dist-upgraded it should be higher than those that support amd legacy driver.

if you are interest to find out more, just compare their xorg version.

if you wish to install legacy in ubuntu based distros, you can use the link
http://www.ubuntuvibes.com/2012/10/how- ... egacy.html

however, on debian based, it is better to use debian sid repos

In LMDE 15 Olivia it's X Server v1.12.4.

You mean, I should activate sid repositories and update all X-related packages?

I am confused on your installed version.

Do you have Linuxmint 15 Olivia? This is ubuntu based.

Or LMDE?? LMDE is Linuxmint Debian Edition. This is Debian based.

There are quite different.


If you have Linuxmint 15 Olivia, then follow the link http://www.ubuntuvibes.com/2012/10/how- ... egacy.html

if you are running LMDE, then better use Debian method.

Sorry, that indeed was confusing! I'm using LMDE.

What exactly do you mean with "Debian method"?

To put it in other words: I don't want the fglrx. I would like to have a stuttering-free radeon driver -- which I had with Ubuntu.
