Okay Gals and Guys! Help

Okay Gals and Guys!

Help much appreciated. I read your suggestions. I can and will upgrade to an additional 2 GB of memory. Details found on line says I can only go up to 4 GB and my ACER already has 2 GB. I will open up the computer to see exactly what RAM is installed, that is one or two sticks before a buy more.

I am unsure how to restrict my computer to just one task. Currently my computer in question is running 2 CPU tasks. So, please advise how to accomplish this task.

Regards,

John

Simplest way would be to change your computing preferences either in the project preferences or via the Managers OPTIONS, local preferences to only use 50% of your processor.

Use at most:

Or you could write an app_config.xml and use the <max_concurrent> tag.

Client Configuration

If you go to https://www.crucial.com/store/advisor you can click on Try our system scanner at the bottom of the box and it will not only tell you which make and model of laptop you have but also what memory you have and how much more you can add. I think it even includes a link to a video to show you how to upgrade to the new memory.

On a side note turn off the screensaver so you can crunch faster, screensavers are pretty pictures but they do not show your actual crunching at this moment and take cpu and gpu time to show on the screen.

No, No not Windows!!  You just needed to abandon Ubuntu earlier ;-) :-).

Well I revisited the AMD GPU driver install and finally got them installed on Ubuntu 20.4.2.  using the instructions earlier in this thread.  I was not getting the same performance out of Win 10 as I was getting out  of Ubuntu.  It was a struggle though.

Okay girls and guys,

I installed an additional 2GB RAM stick to my Acer Aspire 7730Z notebook running Ubuntu 20.10. The performance is better but I still have the same issue. The starsphere loads and I can get a grid by Shift-G but nothing still does happen when I Shift-C, no constellations.

I also updated the Nvidia drivers but still no constellation lines.

Any suggestions on what to try next, if anything? Or am I stuck with what I've got?

I know this notebook is ancient by today's standards but it still works great and I would like to use it in my observatory.

John

Now I don't know if this is a clue or not but looking closely at the dots representing the stars on the starsphere they appear to be tiny squares not dots. So, it seems that there is a screen resolution bottleneck? I have the highest possible screen resolution listed. I experimented with reducing the screen resolution to no effect. Nothing changed.

Here is what I don't understand...If this computer can draw lines for the grid on the starsphere why can't it draw the lines for the constellations?
