how do I increase video card RAM?
I installed slack 10 a couple of weeks ago and at the time I must have indicated that my video card had 16M RAM, but find out now that it actually has 32M. dmesg indicates that my system is seeing 16M:
mga_vid: detected RAMSIZE is 16 MB How can I change my video card settings? I assume I can do this since it asked for this information at installation. |
Go into your "/etc/X11/XF86Config" or "/etc/X11/XF86Config-4" file (first look for the XF86Config-4, if it isn't there then use XF86Config). Now look for the line that says Section "Device", and you should see something like this (here's mine):
Section "Device" Identifier "Videocard0" # Here's an example of a comment (there may be some in yours) Driver "nvidia" VendorName "Videocard vendor" BoardName "NVIDIA GeForce 4 (generic)" # VideoRam 131072 (i commented mine out because it isn't needed) EndSection Now yours will say different things, and for "VideoRam" it should say 16384 - change this to 32768. If it isn't in there (do a search for videoram in the file just to be sure) then here's what I think: Are you 100% sure that you have a 32MB video card? The thing I showed you above (and any configuration during setup) isn't needed at all - in fact, I haven't gotten a prompt for that during setup since the days of Redhat 6.5, about 4 years ago. It's just not needed anymore since all video cards nowadays can be autoprobed. I really am not sure that you have a 32MB card, it would pick it up automatically during setup if you did. |

I think I may have wasted your time. I vaguely recall now that after considering putting in a value for the videoRAM and changing it later that I booted into Suse and got the value from there, so the 16M should be correct. I did check the videoRAM section of my xorg.conf file and it was commented out also, so I suppose my system did get the 16M directly from the card at startup. I am curious why the description of my card online has twice the RAM advertised than I actually have when the card number and name are the same.
