 Posted: Tue Jul 27, 2004 9:58 pm Post subject: 85 Hz framebuffer - RADEON |
 |
|
Before we begin: Yes, I have tried searching the forums. Yes, I'm stupid. Now, let us begin.
How do I get an ATI RADEON to run at 85 Hz (1024x768@85) in the framebuffer? Which driver do I use? vesafb-rcc? vesafb-tng? old radeonfb? new radeonfb? Or do I need to use some fancy hack? This is driving me crazy. |

Which Radeon are you talking about exactly ?
I have my old trusty 8500 running at 1280x1024 @ 85 Hz using the plain vesafb. I have nothing Radeon-related compiled in the kernel.
A little more info on your hardware may be a good start... |

What kernel parameters are you using (/proc/cmdline)?
Which hardware did you want to know about? My video card is a RADEON 9600 XT, my monitor is a SyncMaster 750s, and my motherboard has a SiS745 chipset. I tried using setting up vesafb_modes.h and using vga=0x517, but when I tried to boot, the monitor just went black, and the OSD said it was running at 60 Hz. |

Use radeonfb. Here is a part of my grub.conf:
kernel (hd2,0)/kernel-2.6.9-rc1-mm2 root=/dev/hda1 video=radeonfb:1024x768-32@100
and here .config:
#

| I know this is abit off topic.. I'm using radeonfb so that my laptop can utilize the 1024x600 screen rather than giving me the 640x??? console (waste of space).. and my xorg is set to fbdev. What happens if I set xorg to use its own radeon module? (ATI Radeon LY DDR SGRAM 8 MB ) Will it not use the framebuffer interface and directly access the radeon card? |

Thanks, it finally works. I had some other stuff on my video line that was probably screwing it up. (video=radeonfb:1024x768-32@85,mtrr,ywrap,accel) |

@hotplainrice: this config is likely to screw up your system. there have been reported a lot of problems for the radeonfb & radeon-dri combination. namely, a switch from xorg back to the console (ctrl+alt+F?) would result in a lockup.
i haven't heard of it working, sadly enough. radeonfb's supposed to be a lot faster than plain vesafb, is that correct?

| Yeah, I guess its true.. It feels tiny lil bit slower than the last installation of gentoo where i used the driver in xorg. Unnoticeable until u resize ur window.. |

I use radeonfb and the X11 radeon driver with DRI and xv support.
Works just fine, get ~900FPS in glxgears and I can switch back and forth between the console and X
Using the latest Xorg server (6.7.99.902)
Ofcourse I have a rather ancient
ATI Technologies Inc Radeon Mobility M7 LW [Radeon Mobility 7500]
The relevant config sections are
xorg.conf:
| Code: |
Load "glx"
Load "dri"
Section "DRI"
Mode 0666
EndSection
Section "Device"
Identifier "LaptopCard"
VendorName "ATI technologies Inc"
BoardName "Radeon Mobility M7 LW [Radeon Mobility 7500]"
Driver "radeon"
Option "AGPFastWrite" "true"
EndSection
|
grub.conf:
| Code: |
kernel /vmlinuz root=/dev/hda5 gentoo=nodevfs video=radeonfb:1024x768-32@60 splash=verbose,theme:emergence
|
radeonfb is much faster than vesafb |

thanks for the hint kovid
i'm currently using radeon-drm & vesafb (on radeon m9), and it works flawlessly. i think i'll try the combination with radeonfb the next time everything else works  a working system is an outdated system.
first i've got to solve that "switch to 2.6.8 - cd burner gone" problem.

I believe that all the problems appear only if you're using the ATI binary driver and radeonfb. If you use the "radeon" DRI driver, I think everything will work normally.
