What is your memory usage after Xgl started?

I just want to compare the 3-D desktop memory usage between Vista and Linux Compiz/Xgl. I don't have nvidia GPU, so I can't load compiz. Without compiz, I got 320 MB occupied by loading VNC service, one terminal, one gFTP instance, a 1.5 MB wallpaper, and OSX theme. It could be lighter if I change back to original theme.

What's your numbers?

 

Memory usage on Linux is a very funky thing Make sure you read and understand this. It's more than likely that your memory usage isn't as high as you'd think it is. The memory usage also depends a lot on what services are running... do you still have postfix running on ubuntu? Are you using gentoo completely stripped down? Firewall? All of these things will matter a lot.

That being said, I haven't used Compiz yet, either. Need to do that, just haven't dealt with it at home. I really should do that. Maybe tonight

 

I have my ubuntu running with firewall, 4 tabs terminal when I read 320MB. After I close the terminal and gFTP, it back to 250+MB. I don't have httpd, DB, and some other server stuff. Just close to a desktop configuration.

 

You can run xgl on ati cards. I have an x1600 and it worked fine.

 

i too am running compiz/xgl on x1400 acer 5672wlmi and it runs swimmingly. haven't noticed massive ram usage either, then again i haven't been looking either.

 

then what is your RAM size? 1GB? Swimming good when you open several GIMP pic and playing DVD?

 

I'm hardly noticing any difference (memory wise) between SLED 10 running xgl on my M90 with 512MB ram, and mandriva 2006 on a Thinkpad (no xgl).
Firefox still is the killer wrt memory - its memory usage keeps increasing as time & pages progress.

 

I am running xgl\compiz on my ubuntu with no issues. Actually pretty fast

 

I checked yesterday after closing firefox windows.
With 7 bash terminals, 2 xemacs windows, opera, and an IDE, linux with xgl with 3d desktop turned on was consuming ~300MB.physical memory.

 

I'm on Ubuntu linux and I'm using 130mb of RAM at idle. 140-150 under light use.

 

Which desktop are you running under?

In either case Gnome Terminal or KTerm aren't the most resource friendly terminal emulators available. I know that each instance will use the same shared memory for the most part, but both also set very hefty scrollback buffers by default.

XEmacs is a fairly hefty app too... I still remember the vi zealots wording for emacs, "Eight Megabytes and Constantly Swapping." This was back when 8MB or RAM was considered generous.

 

I was running it under gnome at WUXGA screen resolution.
That emacs quote ...

 

So even resource non-friendly terminal (G/K) will occupy way lower then Vista if using Aero/Compiz effect.

Should I call it "Astala Vista"?

 

In all fairness, I should mention that another laptop (E1505, 1.66Ghz single core, integrated intel 950 graphics, WXGA) was in trouble under 3d desktop, normally it was ok, but videos would play choppy at full screen - cpu would max out at 100%. Dunno whether it was some configuration problem or simply that Xgl is cpu intensive.
My M90 with NVIDIA Quadro FX 1500M, 2Ghz dual core has no problem though - it happily plays video at full screen, WUXGA, cpu @20%.

But yeah, its surprisng how much vista is supposed to eat up RAM.

 

Which driver were you using for the GMA950? Most accelerated drivers support XVideo overlay, which is much more preferable to the fallback, blitting.

Xgl shouldn't be the problem, I presume the Xserver is smart enough to not render something you can't see...

 

I also got problem on setup Compiz using Dell PowerEdge SC430. Poor integrated GPU. Dell even doesn't have PCI-E x16 slot, only x8 slot.

This is really impressive. Are you playing HD Video or plain DVD? XP will occupy 40%~60% CPU load while playing HD video with Nvidia PureVideo driver. Don't tell me Linux beat Vista everywhere.

 

Now, is it just me or are the compiz packages from beerorkid.com for ubuntu broken? Anyone else running into this? I'm not ambitious enough to install it from source. Got XGL running, though.

 

It was not HD video

On HD video @720p spiderman 3 trailer :

cpu usage was hitting 40% at full screen.

 

I dunno, SLED 10 installed it automatically - it was some generic driver I think. But it did say 3d acceleration was enabled.
Disabling the 3d desktop made everything fine for video playback.

 

Yeah, Compiz packages have been taken down from the repos. It's to make way for a new fork of compiz, Beryl. Unfortunately, early versions of Beryl seem to be even slower than Compiz.

I tried installing Compiz last weekend, and find that they had taken it down without the replacement being ready yet, grrrr! I want my spinning cube!
