graphics cards and chips

cast-fish:
you may be right

Compaq laptops indeed often have embedded features......

that is to say it could be 64 vram and 64 system shared Ram. (making 128)

The radeon chip is certainly only 64 meg VRAM according to google.
"Radeon mobility 7500"


I remember my other older compaq laptop here....actually had 128 megs of RAM hard
soldered onto the motherboard. THen next to that is a spare RAM slot where
you can put another 256 max card or lower.

This newer laptop here is a very similar compaq....same era also
but with better graphics chip.

--- Quote from: Misalf on November 12, 2014, 10:32:42 AM ---I asked the webs about VRAM and throw this together real quick:

--- Code: ---sudo lspci -v -s `lspci | grep -m 1 -i vga | awk '{ print $1 }'`

--- End code ---
Look out for stuff like  [size=256M] .

This is what I get:

--- Code: ---00:02.0 VGA compatible controller: Intel Corporation Mobile 945GME Express Integrated Graphics Controller (rev 03) (prog-if 00 [VGA controller])

--- End code ---



About the wait loop, maybe something like this:

--- Code: --- SEC=60
while [ $SEC -gt 0 ]; do
dmesg | tail -5 | grep "Initialized radeon"
echo -ne "Waiting for VGA... $((SEC--)) \r"
done

--- End code ---

--- End quote ---


again, where does this code go?

after the Wait command?
Before the Wait command?
Before everything in the xsession file?

Juanito:
In re-reading the link above, it looks like the delay loop is only needed if you boot directly into the Xorg gui.

If you boot with Xvesa loaded then load Xorg (and the ati/radeon driver and firmware), exit to the command prompt and "startx", the loop shouldn't be required?

If you boot directly to the gui with Xorg (and the ati/radeon driver and firmware) loaded "onboot", then I guess the delay loop will need to come before the first line in ~/.xsession - make sure you use the Xorg command string and not the Xvesa command string.

ok Juanto thanks
