Hi,
I'm trying to get the VESA framebuffer console working with an onboard ATI video controller (lspci reports it as an "ATI Technologies Inc 3D Rage IIC 215IIC [Mach64GT IIC] (rev 7a)"). It mostly works (whereas atyfb didn't work at all) except for one rather odd problem: scrolling doesn't work properly. That is, once the screen fills up, new text is displayed on the last line only and the old text doesn't scroll off the top of the screen as it should. However, if I switch virtual consoles, everthing works fine (that is, I switch from VC 1 to VC 2 and back again). Or if I run a full-screen app such as vi, that also fixes things. This is kernel version 2.4.12; dmesg follows. Please cc replies to me, as I am not on the list.

Thanks,

Yoel
