    this feature gives you more performance like disabling vsync

    but yes this only matters if the fps cound is lower than 60fps.

      Two weeks ago while I was back in Europe, I then received a response to one of my bug reports from March regarding an E-350 TTM crash. In this bug report response, AMD's Alex Deucher cites a patch that was recently merged into Linus Torvald's kernel tree from one of the DRM bug-fix pulls late into the Linux 2.6.39 kernel cycle. The patch in question is drm/radeon/kms: fix gart setup on fusion parts (v2) with a description of "Out of the entire GART/VM subsystem, the hw designers changed the location of 3 regs. v2: airlied: add parameter for userspace to work from."
      This patch is also in the 2.6.38.7 kernel, so it will probably come to Ubuntu 11.04 in the near to medium future.

        Waking up an old thread!

        For guys out there running E350's I have a couple of questions for you.
        1. At this time how has performance stabilized with Linux? Or in other words are birthing pains over in general running Ubuntu or Fedora.
        2. How about the GPU specifically? I know it was a problem initially but have the drivers settled down? Have they gotten faster?
        Thanks

          The open-source driver offers pretty good 2d on Gnome Shell (Unity is quite a bit slower). Haven't tested KWin for some time, but it was generally ok back in July (somewhere between Gnome Shell and Unity in performance). Suspend/resume works fine, 3d works (GL2.1 but I'm not gaming on this system). No video acceleration out of the box. No power management.

          Fglrx 11.10 still doesn't work with Gnome Shell (visible corruption). It works with Unity and is quite fast if you disable vsync in compiz (tearfree in amdcccle is enough). Performance in KDE is ok (not good, just ok). 3d works (GL4.1) but suspend/resume doesn't. No video acceleration out of the box. Good power management.

          You can watch 720p video fine in VLC. Flash, however, is too slow - neither 10.3 nor 11.0 can play fullscreen video smoothly, *regardless* of the resolution, and everything above 360p stutters.

          One surprising thing about this APU is how well it runs virtual machines.

          All things considered, Windows is around an order of magnitude smoother on this APU if you can live with its other shortcomings: faster 2d, faster 3d, smooth 1080p (both offline and flash), lower power consumption (expect around 30-40% more battery life), correct suspend/resume. The experience is much better overall.

          I don't think I can recommend E-series APUs for Linux. Unlike Windows, Linux performance is much more dependent on CPU power (so Atoms are out of the question, too), so a i3 or A6 will offer a much better experience.

          My 2cc.

            Mine still runs the stack originally set up on it, ie linux 3.0, git -ati, git mesa (with mesa periodically updated of these). It worked OK then and still works ok.

            Everything works that I try to do on it, be it compiling, VMs or 3d. It still has the DPMS flicker bug as far as I can tell (the bug is still open; I haven't tested newer kernels), but it's stable. It was also surprisingly fast, I expected worse from that cpu.

              Mine Thinkpad x120e, with E-350 also runs good. I have to disable kwin effects to run fluidly on external 1920x1200 monitor, though. The biggest issue with this laptop is actually the BIOS.

                What about about battery life, how many hours you get, and how much is it in Windows?

                  Thanks guys!

                  It appears as if this is still a work in progress for LInux. That isn't a bad thing as it appears to be far enough along for one use I had in mind. That being a platform for EMC.

                    I'm running an e350 (zotac ad10) as an HTPC running openelec nightly eden builds (xbmc, catalyst 11.10) - It eats through 95% of 1080p .mkvs irrelevant of bitrate, 5% play 'perfectly fine' except all movement on the screen is followed by horrendous macroblocking

                    I knew it was going to be a rough ride for the platform in linux, and any sensible person would have bought an older, cheaper nvidia ION based device...
                    I do hope that things improve in the future, before it becomes completely obsolete.

                    I don't care about game benchmarks, desktop GUI performance or even proprietary/oss drivers (yes, I said it...) - Playing back video is the first thing I'm interested in, ATI are absolutely miles behind in this regard. VDPAU and nvidia binary drivers have worked pretty much flawlessly for as long as I can remember, ATI on linux still remains a disgraceful mess for many users.

                      In Linux with wifi on, about 6 hours of browsing. This is no-flash setup.
                      In windows little more than 6:30-7 hours, no-flash also.

                      For Linux I have followed this wiki: https://wiki.archlinux.org/index.php/IBM_ThinkPad_X120e

                      Do you have such laptop in possession? I want another Linux guy to test something.

                        I have an HP dm1z, which is close enough provided you don't wish to test BIOS-related stuff. (Both systems probably use similar Foxconn motherboards).

                          Well, I actually want to test BIOS stuff. When I enter the bios, and when I exit it without any changes Linux won't boot. It hangs at "Booting the kernel...". I need to turn off the laptop, and then back on. Restart after windows...the same. Any ideas?

                            Not yet. I've one of these on my wish-list and I would have bought one already weren't it for the entire Linux driver mess. No suspend/resume with catalyst and no video acceleration with radeon

                            Well it's good to see that at least you get decent battery life. I'll probably wait for Intel Cedar Trail netbooks to hit the stores though (not much confidence in ATI, sorry to say).

                              Nice data point.

                              Fortunately the intention isn't to view videos if I go this route. One thing of note is that supposedly AMD drivers will get a major overhaul by the end of the year fixing many issues. Hopefully issues with this hardware.

                                Anyone with the dual-core E-350 should benefit from the new Flash Player 11.2 Beta, which introduces support for multi-threaded video decoding. This will not improve video decoding performance on the E-250 as it is a single-core chip. Anyone who has been following the articles on Phoronix will probably know about this already, but I thought I'd mention it just in case. Flash Player 11.2 Beta can be downloaded from Adobe Labs at http://labs.adobe.com/downloads/flashplayer11-2.html
