While my Debian/sarge system with kernel 2.4.26 (radeonfb) runs fine, with kernel 2.6.7 it doesn't show the correct resolution. fbset -i says mode "1280x1024-60" ... Frame buffer device information: Name : ATI Radeon QW ... Still the console is shown with 80x25 resolution. If I start modconf I see the following video modules loaded: cfbcopyarea cfbfillrect cfbimgbld vesafb aty/radeonfb console/font Is that normal? When I "fbset 1280x1024-60" the screen resolution is switched but the screen isn't readable. Any idea how to solve this problem? O.

Neither sets the radeonfb driver the resolution correct (still 80x25 chars) nor is it possible to use fbset (screen unreadable). I've removed all the others framebuffer drivers so only radeonfb is used but with no effect. I've also tried both DVI and VGA but both shows the same effect. Could it be that the radeonfb doesn't handle my ATI Radeon 7500 correct? Or is the ATI Radeon 7500 not very useful? But why does it work with 2.4.26 then? Which is the best framebuffer supported graphics card without a cooler, has a DVI, is reasonably priced (below 100$) and also usable with DirectFB? O.

I am the happy owner of an (ATI Radeon 9200-based) HIS Excalibur 9200 ViVo [1], which I chose for these very reasons (fanless, DVI, low price). Now works fine with both 2.4 [2] and 2.6 kernels as far as I am concerned, but I'm not much into performance tweaks or fancy stuff. All I really care is the high number of rows and columns. I may run tests in case you want to make sure that the card qualifies as "best framebuffer supported graphics", you just have to ask. However, I doubt that support for your current Radeon 7500 card cannot be brought back, especially if it works OK with 2.4 kernels. Changing hardware to workaround software issues doesn't sound like a good policy ;) [1] http://www.hisdigital.com/html/9200vivo.htm [2] I need a patch to be able to force 1280x1024 at boot, but I guess it's related to my flat panel display returning incorrect information, not to the graphics adapter itself. -- Jean "Khali" Delvare http://khali.linux-fr.org/ |

There is a Sapphire Radeon 9600 SE and the Sapphire Radeon 9600 which is 1.5 as expensive but I have no information about them. > However, I doubt that support for your current Radeon 7500 card cannot be > brought back, especially if it works OK with 2.4 kernels.

I'd really like to finally delve into the kbuild facility of the 2.6 kernels and document it here, so everybody can try out new framebuffer drivers or build the DirectFB fusion driver. But as long as my problem persist I can't switch to the 2.6 kernel. Of course a patch which solves my problems would be much better. > [2] I need a patch to be able to force 1280x1024 at boot, but I guess it's > A really simple workaround, which works with any framebuffer, is to put a "/usr/sbin/fbset -a 1280x1024-60" into your "/etc/profile". Before I switched to DVI cable I had this for years with at least 3 different graphic cards, of course first only with "800x600". O.

I have a Radeon 7500 QW (PCI ID 5157) which works just fine on both DVI and VGA, though it was my experience that it liked a 61 Hz refresh rate better for 1280x1024 on VGA. You might try booting with 'video=radeonfb:1280x1024@61' or similar. My card is drunk and reports the DFP size as 1024x768, but the monitor has a correct EDID block and the new I2C/DDC code initializes it just fine on its own in 2.6. -- Chad Daelhousen My opinions are my own, unless UB purchases my soul. |

In my module.conf there is options radeonfb noaccel BTW does anyone know how fbset show the noaccel settings? O. Wyss -- See a huge pile of work at "http://wyodesktop.sourceforge.net/" |
