The subject line of this post identifies the laptop on which I have installed
the latest version of Stellarium. The installation went without issues, but
when I run the program, the frame rate is microscopic to the point of
rendering Stellarium unusable.
Searches of this forum have alerted me to the need for Open GL graphics
capabilities, which the driver currently installed in my Inspiron provides.
But Stellarium runs like frozen molasses regardless of whether I set the
driver's Open GL settings toward performance or quality.
Has anyone successfully run Stellarium on a laptop -- preferably an Inspiron
6000, but I don't think the laptop model is my central issue -- using the
Mobility X300 card? If so, what driver release do/did you use and from where
did you download it?
Thanks for your time,
You seem to have CSS turned off.
Please don't fill out this field.
You will need to find an updated driver for your video display. If the frame
rate is that low you obviously do not have openGL support on the laptop.
Find the reference number for the video display and Google it this should find
you an updated driver.
Thanks for responding, Barry.
I understand the need for OpenGL driver support, and have downloaded two
different drivers that were more up-to-date than the driver I started with.
That driver - actually, both the original driver and the updates I downloaded
- offers several OpenGL preferences settings, but none of those settings
affects Stellarium's slow performance. The driver clearly shows OpenGL
support, but that support has no impact on Stellarium.
That's why I'm asking whether anyone has successfully run Stellarium on a
laptop with the Mobility X300 card; if someone has, it's that driver I want
to find and install.
Thanks again for your time and response.
You have to realise that when you mention a Dell Inspiron 6000, someone has to
look up what a Dell Inspiron 6000 really is.
Is it a laptop from 2005 with a 2.13 GHz Pentium M, 1 GB RAM or 1.3 GHz
Celeron M , 256 MB RAM?
In 2005 we used Stellarium version 0.7.1 and that worked fine on that kind of
Have you tried stellarium.exe --safe-mode?
Safe Mode allows me to use Stellarium on my Inspiron 6000, which is the
outcome I sought. Thank you, Hendrik!
My first run with the program in Safe Mode displayed very satisfactory video
performance. Am I correct that OpenGL support affects the program's
presentation of its content, but not the content itself? So, my using
Stellarium in Safe Mode will not affect the information displayed, but rather
the visual character and quality of the information/graphics displayed?
Thanks again for your help,
