Ati 6450hd boot flashing screen problem!

Well I am a big fan of Linux. I had the same problem with Fedora and Ubuntu too but I solved it using the failsafe option (on fedora I solved it out of luck :P)

My problem is that the screen is flashing!

When I boot using the “nomodeset” command the screen works and I can see everything but it doesn’t let me go to my desktop, I just have a blank terminal like the one below:

And when I press CTRL+ALT+F1 and I type init 3 (with root login) after I go back to the blank terminal with CTRL+ALT+F7 I see this and the whole process stuck at “Graphical Interface”:

I am using version 12.3 with KDE desktop. I have nerver tried to install gnome desktop.
I have this problem with Graphical Interface at recovery mode too. I’ve tried both safe settings and acpi=off, but to no avail. A previous version of opensuse worked like a charm in my pc but I don’t remember which version it was, as I installed it 2 years ago.

Please hlep me! I am desperated and I love opensuse! Thanks!

What video card?

Ati radeon hd 6450 2gb (saphirre).

Can you get to a terminal login prompt?

If so log in as root and run yast. Add the ati repo and install the ATI driver.

I can but I can’t connect to the internet with Opensuse so I can download the drivers.

hmmm how are you connecting? Wireless? if so use a wired connection it should work if you are booting to init lev 3. You can get the drivers from ATI/AMD but you will need additional items to compile that are not part of the normal install.

I haven’t try wired connection. I am gonna to try it at say the results! Thanks for your assistance :slight_smile:

You may also try to add nomodeset at the boot

pres ‘e’ then find line starting with linux go to the ens (note it wrpaes so go to the real end) add a space and nomodeset the press F10 to continue with boot that may get you to a GUI but you need furthr instruction if you want to run normally like this. Best to just install the propitiatory driver.

I’ve already tried that and everythingis working good but it boots me at blank terminal page. “I believe I have written this and at my first post too”.

why would you say that?

[quote="“billpao,post:5,topic:91683”]

I can…[/QUOTE]when you get to the console prompt, what output do you get for:

cat /proc/cmdline

and, for that matter, what does your xorg log say (have a look through it and see if it states an error)?

cat /var/log/Xorg.0.log | less

if you can, post it (the contents of the log file) to SUSE paste and provide a link http://paste.opensuse.org/

With most cases it fixes the problem. The OS drivers in 12.3 are a bit wonky. and if they won’t work the best avenue is to install the proprietary drivers. And in any case the proprietary drivers have noticeably better performance.

Unfortunately, I can’t copy the log file because I have access only to a terminal and I am unable to go at desktop. Also, the wired connection isn’t working at opensuse to install the drivers via teminal.

okay, do you have a usb pen drive available? if so, you mount the pen drive and then copy the xorg log file to the pen drive, which you can then read on another system

I am writing this message from Opensuse :D. I finally managed to install the drivers by running terminal level 3 and with nomodeset. Then I just typed init 3 and installed the drivers. Thanks for your assistance.
