kewlix: i'm looking for a video card (free drivers) on AGP slot, is the ATI 9250 the best ?
the-me: kewlix, that should be a good card for it
xAFFE: hi folks :)
simmerz: is there any progress on acceleration in the radeonhd driver?
libv: tri: hi
tri: somebody here have working xorg.conf file for a t60 with the radeonhd driver to share ?
tri: ibm t60/x1400
libv: tri: what sort of problems are you seeing?
libv: tri: as there really shouldn't be much in the way of configuration
tri: hm I thought I can run the startx without any xorg.conf file but that isn't working
tri: I got a "cannot run in framebuffer mode" - but maybe this is just a configure error on my machine
tri: hm there is also the message "new driver is "ati" " ?
libv: if it doesn't say radeonhd all over the place, then it isn't our driver
libv: tri: try just using Driver "radeonhd" in the device section
libv: all should be well after that
tri: yes, thanks :-)
Zhenech: just wondering
Zhenech: any ideas about the brightness change on laptops?
libv: Zhenech: yeah, we probably should keep on allowing the direct io access, but we should then also do things so that some other issues aren't exposed anymore (by setting some scratch registers appropriately)
libv: Zhenech: but it's been confirmed from all sides that this is not a surefire way of doing things :)
Zhenech: libv, aha, k
Zhenech: was wondering because radeonhd is the only free driver having such problems
ryanpg: evening libvde
ganymede: hello, i was wondering if it is even in the silicon of any radeon chips to implement the extension GLX_EXT_texture_from_pixmap, or whether that simply a driver limitation
airlied: ganymede: driver limitation
airlied: ganymede: its just a way to get a texture handle from an X pixmap
airlied: has nothign to do with hardware at all.
ganymede: airlied: i'm not too familiar with this, but is it the silver bullet that will allow compositing opengl windows?
airlied: ganymede: no we already have that..
ganymede: airlied: "we?" as in fglrx?
airlied: ganymede: there isn't one thing we need to get compositing opengl windows, we needs lots of things..
airlied: we as in X.org
ganymede: ah, i haven't played around with the xorg drivers. the needed version wasn't in my package manager
ganymede: i'm using an R300 and apparently, the xorg drivers have 3d support for that, but i'd need to get my hands dirty with an SVN compile
airlied: this channel is for the open source drivers.. fglrx is #ati
airlied: ganymede: wierd it works for me witgh most distros.
airlied: any distro from the last year should do r300 fine..
airlied: still won't get opengl window compositing..
airlied: as the necessary other bits to do that in the open source drivers aren't in place yet
ganymede: oh okay, thanks for that information
ganymede: is this an appropriate place for general video card discussion? i wanted to ask about the possibility that in the future, 2d acceleration will be dropped in the silicon altogether, and everything will be done in 3d, since it is a superset? i was recently working on one of those alternatives to xorg where everything exists in opengl land (sort of like project looking glass) i'm no expert, but it seems like 2d pixmaps is a thing of the past, and
ganymede: ditching it would simplify driver/chip development (although there'd have to be a great migration into the new system)
ganymede: there were a couple of other display managers that were entirely in 3d, ditching the concept of drawing windows onto 2d planes, many cited a reason as simplified driver development
airlied: ganymede: not totally suitable, but most chips already dropped the 2D ..
airlied: r600 has no 2D..
ganymede: so in that case, the 2d acceleration code just uses the 3d parts of the card?
airlied: yes.. also render acceleration on most cards requires using the 3D engine..
ganymede: oh okay, i like the sound of that =)
airlied: we also have XGL and glucose which can convert X 2D drawing into 3D ops.
airlied: and then execute them via an OpenGL driver
ganymede: 2d has always bothered me, since humans live in a 3d world, 2d seemed very artificial and counter-intuitive
airlied: monitors are flat :)
ganymede: although the pixel-grid concept was a limitation of old hardware
airlied: and watch people playing something like descent and realise how we mostly do live in a 2D world :)
ganymede: XGL was a good start but rather than simply making the display manager live in opengl land, the apps still draw onto a pixel grid. i began a project where the applications also live in opengl land
ganymede: anyway, now i'm getting offtopic
