Hello list,
I have been using EMC2 with 8.04 now for some time on an medium old PC with and having a consistent latency below 10 000, pretty happy with it. My HW is a 3 axis mill, stepper motors, Gecko 540, Motherboard says ASRock 775i65G, 865 chipset, Pentium4 3GHz and nvidia MX400 graphics. As a consequence of bad weather and too little to do, I thought I'll give Ubuntu 10.04 a try. So put in a brand new hard disk and do a fresh install from the live USB stick. Installation went without a glitch. Good, now do a quick check on latency, is now over 200 000, not so impressive, clearly display related it jumps around when resizing the glxgears display. So I change my nvidia board to an ati radeon, this brings latency to 25 000. Tried ATI and VESA drivers, no difference. Tried the GFLRX driver but this gave me a seg fault in glxgears (libGL.0). I could not resolve this so I simply reinstalled EMC2. BTW. Using the VESA driver was a little involved. Driver "vesa" in xorg.conf gave me " (EE) VESA: Kernel Modesetting driver in use, refusing to load " https://wiki.ubuntu.com/X/KernelModeSetting taught me this: Creating a file with echo radeon modeset=0 > /etc/modprobe.d/radeon-kms.con And executing update-initramfs -u made it possible to load VESA. Didn't note any performance difference though. To summarize, moving from 8.04 to 10.04 brings my latency from 10 000 to 25 000, is there something more I can do? Maybe stick with 8.04 (I still have it installed) ? Any other suggestions for me to try are welcome! ------------------------------------------------------------------------------ Beautiful is writing same markup.
