[gentoo-user] xorg-x11, $VIDEO_CARDS & binary packages

[Alexander Puchmayr]

Hi there !

In my /etc/make.conf is a line 
VIDEO_CARDS="nv nvidia"

If I make a "emerge -pv xorg-x11", I get the following output

...
[ebuild  N    ] x11-drivers/xf86-video-nv-1.0.2.0  USE="-debug" 0 kB
[ebuild  N    ] x11-libs/libXv-1.0.1  USE="-debug" 0 kB

-s3virge -savage -siliconmotion -sis -sisusb -tdfx -tga -trident -tseng 
-v4l -vesa -vga -via -vmware -voodoo" 0 kB

Note the VIDEO_CARDS-variable has "nv" and "nvidia" set, which is what is to 
be expected.


If I add a -k for binary packages to the emerge, I get the following output

...

Note the different VIDEO_CARDS, which seems to be the default and hence 
installing *ALL* optional video drivers.

I don't want all the drivers I don't need, nor do I want to recompile all of 
xorg-x11; Is there any possibility to get around this quite odd behaviour?

Um, >=x11-base/xorg-x11-7.0 is a meta build.  It is only there to
depend on all of the modular X packages.  Since none of those showed
up, the only things that will get rebuilt by your first command is
libXv and xf86-video-nv.

Well, I think I got the conecpt behind meta packages. My question was why do 
I get a different content of the VIDEO_CARDS-variable when I specify "-k" 
in emerge or not???

You can't change the USE flags a binary package was built with.  Binary 
packages are built with a certain set of flags, and they're stuck with 
that set of flags until you recompile the whole thing.

I'd recommend you emerge --nodeps xorg-x11 in order to change its 
USEflags to the ones you want (no compilation necessary), and then 
emerge -k to pull in the binary packages depended on by its new flags, 
which will save you the compiling time.

Nope, doesn't work. Same problem. I emerged with --nodeps the xorg-x11 
package, with exactly the video-cards I want. Then I've tried the -k as you 
suggested, and still *ALL* other video-drivers are shown in the list, and 
VIDEO_CARDS did not show the same content as without -k.

Do you have buildpkg in FEATURES?  If not, you might need to do:

emerge --nodeps xorg-x11
quickpkg xorg-x11
emerge -k xorg-x11

If you don't have buildpkg in FEATURES, and don't do the quickpkg
step, then the second emerge will again look at your existing binary
package of xorg-x11, and use the settings from that.

Haha, silly me.  I forgot it would use the binary xorg-x11 anyway.  How 
about emerge -k --depsonly xorg-x11?

Same in green :-(

It seems as if VIDEO_CARDS is ignored as soon as I specify -k ...

BTW: --onlydeps, not --depsonly

Because it uses the VIDEO_CARDS variable from the binary package.  In
other words, the VIDEO_CARDS variable of your build system does not
match the target system.  As Randy said, you cannot change the
useflags (and VIDEO_CARDS are a kind of useflag) of a binary package.

A quick demonstration:

My normal xorg-x11 merging:

carcharias src # emerge -pv xorg-x11
[ebuild   R   ] x11-base/xorg-x11-7.0-r1  USE="-3dfx"
INPUT_DEVICES="evdev keyboard mouse synaptics -acecad -aiptek -calcomp
-citron -digitaledge -dmc -dynapro -elo2300 -elographics -fpit
-hyperpen -jamstudio -joystick -magellan -magictouch -microtouch
-mutouch -palmax -penmount -spaceorb -summa -tek4957 -ur98 -vmmouse
-void -wacom" VIDEO_CARDS="fbdev nv nvidia vesa -apm -ark -chips
-cirrus -cyrix -dummy -fglrx -glint -i128 -i740 -i810 -imstt -mach64
-mga -neomagic -nsc -r128 -radeon -rendition -s3 -s3virge -savage
-siliconmotion -sis -sisusb -tdfx -tga -trident -tseng -v4l -vga -via
-vmware -voodoo" 0 kB

Since my binary packages were built on this system, using the binary
package is the same:

carcharias src # emerge -pv -k xorg-x11
[binary   R   ] x11-base/xorg-x11-7.0-r1  USE="-3dfx"
INPUT_DEVICES="evdev keyboard mouse synaptics -acecad -aiptek -calcomp
-citron -digitaledge -dmc -dynapro -elo2300 -elographics -fpit
-hyperpen -jamstudio -joystick -magellan -magictouch -microtouch
-mutouch -palmax -penmount -spaceorb -summa -tek4957 -ur98 -vmmouse
-void -wacom" VIDEO_CARDS="fbdev nv nvidia vesa -apm -ark -chips
-cirrus -cyrix -dummy -fglrx -glint -i128 -i740 -i810 -imstt -mach64
-mga -neomagic -nsc -r128 -radeon -rendition -s3 -s3virge -savage
-siliconmotion -sis -sisusb -tdfx -tga -trident -tseng -v4l -vga -via
-vmware -voodoo"

Now "simulate" a system with different VIDEO_CARDS by adding fglrx:

carcharias src # VIDEO_CARDS="fbdev nv nvidia vesa fglrx" emerge -pv xorg-x11
[ebuild  N    ] x11-drivers/ati-drivers-8.26.18-r1  USE="-acpi -doc
-opengl" 23,160 kB
[ebuild   R   ] x11-base/xorg-x11-7.0-r1  USE="-3dfx"
INPUT_DEVICES="evdev keyboard mouse synaptics -acecad -aiptek -calcomp
-citron -digitaledge -dmc -dynapro -elo2300 -elographics -fpit
-hyperpen -jamstudio -joystick -magellan -magictouch -microtouch
-mutouch -palmax -penmount -spaceorb -summa -tek4957 -ur98 -vmmouse
-void -wacom" VIDEO_CARDS="fbdev fglrx* nv nvidia vesa -apm -ark
-chips -cirrus -cyrix -dummy -glint -i128 -i740 -i810 -imstt -mach64
-mga -neomagic -nsc -r128 -radeon -rendition -s3 -s3virge -savage
-siliconmotion -sis -sisusb -tdfx -tga -trident -tseng -v4l -vga -via
-vmware -voodoo" 0 kB

So it recognized that I added fglrx,and wants to add
x11-drivers/ati-drivers.  Now let's try that with the binary package,
that now does not match my "target" system:

carcharias src # VIDEO_CARDS="fbdev nv nvidia vesa fglrx" emerge -pv
--usepkgonly xorg-x11
[binary   R   ] x11-base/xorg-x11-7.0-r1  USE="-3dfx"
INPUT_DEVICES="evdev keyboard mouse synaptics -acecad -aiptek -calcomp
-citron -digitaledge -dmc -dynapro -elo2300 -elographics -fpit
-hyperpen -jamstudio -joystick -magellan -magictouch -microtouch
-mutouch -palmax -penmount -spaceorb -summa -tek4957 -ur98 -vmmouse
-void -wacom" VIDEO_CARDS="fbdev nv nvidia vesa -apm -ark -chips
-cirrus -cyrix -dummy -fglrx -glint -i128 -i740 -i810 -imstt -mach64
-mga -neomagic -nsc -r128 -radeon -rendition -s3 -s3virge -savage
-siliconmotion -sis -sisusb -tdfx -tga -trident -tseng -v4l -vga -via
-vmware -voodoo"

See, no fglrx and no merging of ati-drivers, even though fglrx is in
my VIDEO_CARDS.

HTH,

Maybe I'm wrong, but binary packages are BINARY (-k), so, you can't
change their USE, because they're already compiled, they'll use the
flags that were used by the time the package was created. If you
install it creating binaries (FEATURES="buildpkg" emerge xorg-x1) now
with another USE or emerge it and create the binaries after it
(quickpkg), then you may get what you want when you try and reinstall
it.

Someone will correct me if I'm wrong, I'm using logic here, not
exactly empiric knowledge ;)

But it's right :-). Even if xorg-x11 may be a "meta" package, it's a
package, after all. And thus it's set of USE flags (and those
additional configuration vars that are listed in verbose output of
emerge) was *fixed* when the binary was created. That makes perfectly
sense -- if you want it to get rebuild, don't use -k. And it's a meta
package, it does download nothing at all. So having a binary of it
doesn't make much sense if there's a very heterogenous number of
clients that make use of the binaries. For restoring the machine that
built the binaries, however, it makes perfectly sense (as long as
hardware doesn't change).
