Screen refresh is slow after reinstallation

After playing with installations of Linux via Boot Manager and resizing old legacy size logical partitions, it was evident to me that a clean re-installation of EcS 1.2R was in order. This was done, fine, with everything seeming to be running as before. However, I notice now that when I either drag a window across the desktop or scroll a full screen window, the video refresh is extremely slow. Nothing has changed in my hardware settings. Just wondering if there was an upgrade to my Scitech driver in recent years that I cannot access anymore. Curious

Thanks in advance.

Hi,

what display driver did you use during the reinstallation? Serenitys Snap-SE, the base VGA or Gengradd?
For people having their own (registered) SNAP and doing a eCS pre-2.0 install, I usually recommend to use plain base VGA and then install the SNAP once the setup is complete.

It might also be that you have forgotten to update something else in between... USB/ACPI drivers? This *can* have an impact on resource assignments to devices. If you are having a "full" version of SNAP - did you perhaps change any "SET" parameters for it in your previous config.sys which are not entered by now?

Also, double-check if your machines BIOS settings are correct - who knows. Things like write-combining (good if enabled) or "Assign IRQ to VGA" (bad if enabled) can have an impact. I know, you said you didn't change things... but better check twice.

BTW: AFAIK, SNAP 3.1.8 was the latest "full" version they released... not sure though as I don't have my Scitech at hand right now. ;)

HTH,
Thomas

I may be wrong, but I was under the impression, that the SNAP 3.1.8, that comes with eCS 2.0, is actually the full version. In any case, SNAP is now free. See:

Check System Setup-> Screen, to see what mode it is running in. On my new systems, it runs in VESA VBE 2.0 mode, which is a lot slower than whatever it was running in with my old ATI X300 card, in my old system. Panorama works about the same (it is VESA 2.0 based), until I get the buffer mode (or whatever they call it) going, and then it runs somewhat quicker. The main reason why I don't use Panorama, is that it will not allow Doodle's Screen Saver to turn off the screen, while SNAP does allow that, and I am rarely impacted by the slower operation.
