Hi, Actually if you read through my report I finally figured what is the problem. It is not ubuntu's fault. Xorg upstream simply decided to rip XAA from Xorg 1.13, and 14.04 has Xorg 1.15 or something like that. So basically in 12.04 there was no hardware acceleration either unless you defined 1208x1024 which fits in matrox 200ge's memory for framebuffer. This option is still ok on 14.04 so if you don't need 1920x1080 then it should be reasonable quick (in my case I have a big monitor with FHD resolution so I wanted to use it like in 12.04 where XAA could handle the desktop pretty fine at this resolution.
Anyway, I did a nasty hack and avoiding the dependency hell (downgrading to older X would make million otherwise working packages to change as well) so I simply copied some files from 12.04 precise: the files were: /lib/x86_64-linux-gnu/libudev.so.0* /usr/bin/Xorg /usr/bin/cvt /usr/bin/gtf /usr/lib/xorg/modules/* This downgrades Xorg to precise latest with XAA. To avoid breaking the X system with later X upgrades you have to hold the following packages: xserver-xorg-core xserver-xorg-input-evdev xserver-xorg-input-mouse xserver-xorg-input-vmmouse xserver-xorg-video-mga xserver-xorg-video-vmware Then just restart X and you are enjoing mga200 with XAA and enough performance for 1920x1080p I am attaching the tar.gzipped files from precise I saved for later for you in case you wanna experiment. If you are going to apply it, backup the files which will be overwritten for any case. regards Zoltan 2014-05-22 4:10 GMT+02:00 maddie <1316...@bugs.launchpad.net>: > Any update? > > Having the same problem on a Dell PowerEdge T420, 2D acceleration is not > working on 14.04, whereas on 12.04 it worked just fine. > > -- > You received this bug notification because you are subscribed to the bug > report. > https://bugs.launchpad.net/bugs/1316035 > > Title: > matrox g200eR2 is unclaimed in 14.04 > > Status in “xorg-server” package in Ubuntu: > New > > Bug description: > On a certified Dell PowerEdge T620 server > (http://www.ubuntu.com/certification/hardware/201207-11426/) > > The matrox video card is not recognised: > lspci | grep VGA > 0a:00.0 VGA compatible controller: Matrox Electronics Systems Ltd. > G200eR2 > > lshw -C display > *-display UNCLAIMED > description: VGA compatible controller > product: G200eR2 > vendor: Matrox Electronics Systems Ltd. > physical id: 0 > bus info: pci@0000:0a:00.0 > version: 00 > width: 32 bits > clock: 33MHz > capabilities: pm vga_controller bus_master cap_list > configuration: latency=64 maxlatency=32 mingnt=16 > resources: memory:d8000000-d8ffffff memory:deffc000-deffffff > memory:de000000-de7fffff > > Thus xserver is not hardver accelerated. > > Also /dev/dri and /dev/dri/card0 is missing. > > kernel module mga is not loaded, although if i manually load by modprobe > it works fine > modprobe mga > lsmod | grep mga > mga 40811 0 > drm 302817 1 mga > > To manage notifications about this bug go to: > > https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1316035/+subscriptions > ** Attachment added: "xorghack.tgz" https://bugs.launchpad.net/bugs/1316035/+attachment/4117427/+files/xorghack.tgz -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1316035 Title: matrox g200eR2 is unclaimed in 14.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1316035/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
