Bugzilla Bug 194503

enotice reports:

Package: xorg-server-1.4-r2
 * Users of reduced blanking now need:
 *    Option "ReducedBlanking"
 * In the relevant Monitor section(s).
 * Make sure your reduced blanking modelines are safe!
 * You must rebuild all drivers if upgrading from xorg-server 1.3
 * or earlier, because the ABI changed. If you cannot start X because
 * of module version mismatch errors, this is your problem.

It would help VERY MUCH if we were given a handy command to run; example for
principle:

emerge -ep world | cut foo | grep -v bar | xargs emerge

I will try to work one and give feedback.

Without this, many users will be in big trouble doing what's proposed. Do not
expect users to known how to list such thing; please provide a ready-to-use
solution.

PS: cant we remove this message about reduced blanking ? I read this since
months, I am bored of it ...

emerge -ep world |grep x11-drivers | cut -d "]" -f2 | cut -d " " -f2 |sed
's/x11-drivers/ =x11-drivers/' | xargs emerge -v1p 

looks nice to me

Shouldn't we add some x11-libs and x11-proto such as x11-proto/renderproto or
x11-libs/libXrender ?

Dont forget to remove the "-p" thing if you like this :)

I tell you in 20mn if this is "enough" to fix whats said in the ewarn, and if X
starts correctly.

bug 194506 blocks this because as long as I cant upgrade drivers, proposed
command can not be "checked": as long as test fails, I conclude the command
does not let X work again, thus, does not perform the advice given in ewarn ...

ATM, I consider my machine a unfunctionnal: X is broken.

I added a little bit to xorg-server-1.4-r2 to try printing the drivers. Let me
know how you like it.

No, that's not <<handy>> for newbs:

As I said, read ewarns of GCC or OpenSSL, they explicitely give the command to
run. Having to copy/paste a dozen of things is neither handy, nor
user-friendly; it should be something as simple as
$ revdep-rebuild --library libcrypto.so.0.9.7
or
$ fix_libtool_files.sh

I proposed
emerge -ep world |grep x11-drivers | cut -d "]" -f2 | cut -d " " -f2 |sed
's/x11-drivers/ =x11-drivers/' | xargs emerge -v1p 

I understand that print_installed is safer; thus, we may end-up with something
like
ewarn "To rebuild required things, run:"
ewarn "emerge -va1 " `print_installed x11-drivers/ |sed 's/\* / =/ |xargs echo
-ne'` " ."
( command not tested)

if you see what I mean ...

(REOPENing)

You did not answer me about if we should also adivse to rebuild some x11-proto/
, x11-libs/ or things like media-libs/svgalib , DRM ... that may also be
affected ...

You can't run emerge from inside emerge, that's why I put together an alternate
command. But I'll see whether I can get the actual output in there -- it might
get interrupted by a bunch of stars '*' though, so it's reduced to copy and
paste anyhow. As for other packages, just the driver ABI was broken.

You got me wrong:

ewarn "to fix stuff run this:"
ewarn "emerge -ep world |grep x11-drivers | cut -d "]" -f2 | cut -d " " -f2
|sed
's/x11-drivers/ =x11-drivers/' | xargs emerge -v1p "

does NOT run emerge inside emerge ... 

(but actually, what I propose in #4 is bad, since I rely on sed inside an
ebuild, what *IS* bad). I think you misunderstood at least one of my comms.

Oh, I see. I must not have seen the ewarn in front when you mentioned emerge
before. I do prefer the current way of getting packages though, as it's much
faster and easier to tweak for people using pkgcore etc, and it also sticks the
package names into the log. I'll change it up a bit to print without the
versions so it's easier to paste into an emerge command.

Why do you need versions there? Plus users completely ignore the messages
anyway, so it's just mostly ebuild bloat. Stick a simple command there for the
unlikely possibility that someone actually read it and be done with it.

emerge portage-utils; emerge -1 $(qlist -CI x11-drivers)

Should be fixed in 1.4.0.90, please reopen if it's not.

Still not. What _I_ would have consider handy would have been:

 * You can generate a similar list at any point using this command:
 * emerge portage-utils ; qlist -I -C x11-drivers/ | xargs emerge

instead of
 * You can generate a similar list at any point using this command:
 * emerge portage-utils; qlist -I -C x11-drivers/
in xorg-server-1.4.0.90

I will explain my point one more time: the thing is that the user should have
to recopy only one command line; the actual message requires the user to
copy/paste all lines, that are 20 drivers on my system (should be around 6 for
common usrs).

The problem is not getting a list of drivers to recompile, but, to list and
recompile them in the same command. Were my previous explanations ambiguous ?
Having to copy/paste more than 2 lines is NOT newbe-friendly.

The emssage should not even list installed drivers, but, only say:

 * You must rebuild all drivers if upgrading from xorg-server 1.3
 * or earlier, because the ABI changed. If you cannot start X because
 * of module version mismatch errors, this is your problem.
 * You can list and recompile them by running:
 * emerge portage-utils ; qlist -I -C x11-drivers/ | xargs emerge -v

I am sorry for typo; emerge command should in fact be:

xargs emerge -v1

This is Gentoo, which isn't a newbie-friendly distribution. Are we trying to be
so "friendly" that we assume people don't know how to use pipes and xargs?

I am trying to automise things, so that other users wont have to "think".
Nothing bores me more than having to copy/pasted dozen lines, so, if I can
avoid this for friend, I will.

But since nobody else joined this bug by the mean times, it means I am the only
Gentoo user thinking this way. So, let's close.

It's not a matter of helping dumb people, but a matter of not making every
single user having to trick this, when the tip help could be usefull for every
one.
