Re: [compiz] Dual-screen compiz mostly working
Most of these problems are all the same problem, from the look of it. Your screen resolution is higher than your video card's maximum texture size. This is simply a hardware limitation. You were absolutely right after all. The strange limitations i was seeing was because i was changing between screen resolutions w/ xrandr while compiz was running. If i use xrandr to set the total resolution of both screens to 1400x1818 and *then* start compiz it works beautifully. Some of the other oddities were fixed by xorg.conf tweaking. thank you everyone for the valuable help. ~mck -- Buddhism has the characteristics of what would be expected in a cosmic religion for the future: It transcends a personal God, avoids dogmas and theology; it covers both the natural and the spiritual, and it is based on a religious sense aspiring from the experience of all things, natural and spiritual, as a meaningful unity.

Compiz doesn't render the full width when the screens are side by side. Even when vertically position i cannot have the second screen at 1600x1400 for the same reason. Is this a limitation of compiz? Are there plans to fix/improve it? This is most likely due to the coordinate limits of the hardware 3D engine. That could be worked around in the Mesa driver, but there would still be the texture size limit others pointed out, and that can't be worked around in the drivers with the current GLX_EXT_texture_from_pixmap API so it would have to worked around by different means by compiz. - my fonts are not nearly as clean and crisp under compiz as they are under metacity. It's like the fonts are thick and fuzzy under compiz. I've seen this before, I think it happened when /apps/compiz/general/allscreens/options/texture_filter is set to 2 (maybe also 1) and /apps/compiz/plugins/cube/screen0/options/inactive_opacity was set to less than 100 (which I think is a bad idea in general). compiz will always use NEAREST filter when windows aren't transformed and the texture_filter option will only change the filter that is used for transformed windows. Anyhow, if the BILINEAR filter happens to be used when a window isn't transformed, a decent OpenGL implementation should provide BILINEAR texture filtering that is accurate enough to not produce a visible difference between NEAREST and BILINEAR filters in the non-transformed case. -David ___ compiz mailing list compiz@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/compiz
[compiz] Dual-screen compiz mostly working
I have dual-screen compiz-fusion finally working on my ATI Radeon Mobility X600.

Compiz events cause it to redraw but application events do not cause a redraw! This is a showstopper for me so i'm still using metacity when in dual- screen setup. I tried all sorts of tweaks onto my xorg.conf but nothing seemed to work. I thought it was maybe DynamicClocks but turning it to off didn't help. Do any of the compiz gurus know what might be at fault here or what i might do to provide better information on the bug? - my screens must be vertically positioned. Compiz doesn't render the full width when the screens are side by side. Even when vertically position i cannot have the second screen at 1600x1400 for the same reason. Is this a limitation of compiz? Are there plans to fix/improve it? - my nautilus background ( desktop icons) disappear replaced with the partially transparent cube. I haven't quite pinned down what causes this but it does very rarely also occur on single-screen setup. Opening more applications seems to aggravate it occurring, and so does the Reflection plugin. - my fonts are not nearly as clean and crisp under compiz as they are under metacity. It's like the fonts are thick and fuzzy under compiz.

Are there plans to fix/improve it? Is a hardware/driver limitation. You can't have textures larger than 2048x2048, and your (total) desktop has to be one texture. I think that it is technically possible for Compiz to work around this limitation; there was a patch for a copy-mode rendering plugin that theoretically could allow a graceful fallback for textures larger than the hardware maximum. I'm not sure if the patch actually had that behaviour, and no-one seems to be trying to implement it. Where can i find this patch or copy-mode rendering plugin? (I'd like to atleast give it a try).
