[gentoo-user] Xorg.. twm not starting and terrible performance with fluxbox

[Mrugesh Karnik]

Well hi again,

It took longer than I expected to change the server. Anyway.

The VIA Unichrome situation turned out to be a no-go for me. I had to 
install an NVIDIA GeForce FX5200 on the machine and get X running.

I think this whole thread and me compiling various Xorg versions about 8 
or 9 times was a waste of time. Because as it turns out, fluxbox, even 
on the nvidia drivers took ages to open xcalc and such. The only 
difference was that, the mouse pointer moved properly with nvidia 
drivers when fluxbox was trying to open xcalc. With vesa, the pointer 
lagged like hell!

Something interesting did happen though. I had that "Unknown device" in 
my lspci output for both Gentoo and FC4 when I was on VIA Unichrome. Now 
after switching to nvidia, I can see a Host Bridge properly identified 
in its place. I wonder why that would be?

I still am confused about one thing though... which exactly is the 2D 
driver for VIA Unichrome?

I apologise to those who wasted their time reading this thread and 
replying in it.. but I found the problem worth investigating and I am 
still intrigued by it..

Regards and a sincere thanks,
Mrugesh

Flaky hardware?  Timings too fast in the BIOS?

Kernel misconfigured?  When the vesa driver doesn't give acceptable 
performance, there is something wrong.  You might want to actually 
answer the questions I asked earlier.

I couldn't answer the questions back then due to a number of factors. 
Anyway, I still can't post the output of lsmod from my FC4 system, as I 
won't be able to boot into it for another couple of days atleast.

Well, somewhere deep in the BIOS peripheral settings, there are 
things like "Enable AGP Fast Write" or similar.  Set all those 
things to Off or Disabled.  You wil want stability first, speed 
maybe later.  It probably won't make a difference, but it at least 
excludes one possible source of problems.

You've said you have an MSI K8M800 motherboard.  Looking at 
http://www.msicomputer.com/product/p_list.asp?class=mb&cpu=3, such 
boards only support "Sempron 2600+, 2800+, 3000+, 3100+, 3300+", 
not a 2500+.  This may not be a problem, but then again, it might 
not be listed for a reason.

No "sse" USE flag?  You could try adding it and re-emerging Xorg.

> Anything else you'd like to know?

To confirm your exact CPU, 'cat /proc/cpuinfo'.
An 'lsmod' on this system under Gentoo.
An 'emerge -pv xorg-x11'.
A 'cat /etc/X11/xorg.conf'.
And 'grep "^(--\|^(WW\|^(EE" /var/log/Xorg.0.log'.

Yeah, those were all disabled when I was running Unichrome. I've turned 
them all on for NVIDIA though. No stability problems.

Hmmmm. Well I checked the motherboard manual when I bought this computer 
and it says "Supports AMD K8 64 bit processors (Socket 754).

Well, 3dnow, mmx and sse are all masked in the amd64 profile anyway...

It is an AMD Sempron 2500+

This is the current one. Back with Unichrome, I had via and drm loaded 
in place of nvidia.

Nothing fancy in there I guess.

Well, I can't get you those results for Unichrome on this Gentoo 
machine. It's all NVIDIA in there now, even in the FC4 logs...

That's the motherboard actually. K8M800-CE is the chipset name from VIA.

[gentoo-user] Xorg.. twm not starting and terrible performance with fluxbox

[Mrugesh Karnik]

Hi,

I just installed Gentoo on an AMD64 Sempron machine. RAM is not a 
problem.. 1GB of it.

I just emerged xorg-x11. The graphics card is VIA Unichrome onboard. I 
have a perfectly fine working FC4 system. I used the FC4 xorg.conf file. 
First ran Xorg -configure. Kept all the paths from Gentoo and filled in 
stuff like mouse, keyboard, monitor and graphics card configuration from 
the FC4 file. I tested the file with X -config /root/xorg.config.fc4 and 
it worked fine. I then copied it to /etc/X11/xorg.conf and gave startx. 
But twm refused to start. I could just a see a black screen with a black 
X mouse pointer in the middle. I moved it and it was lagging very badly. 
So I killed the X server and emerged fluxbox.

Fluxbox started fine. But when I tried to open xedit.. it went terribly 
slow.. Same thing with xcalc. People in #xorg on Freenode told me that I 
needed to look for via_drv.o module. I didn't find it. Xorg doesn't 
install it. vesa gives very bad performance as stated above. 
Interestingly, vesa is what FC4 uses and it runs absolutely fine!

What am I to do? I would appreciate any help anyone can offer!

Thank you,
Mrugesh

I don't use it, but it looks like I got a via_drv on my install of
xorg-x11.  Which version of xorg-x11, and what USE flags?

Hmmm. I am using the stable version. That's 6.8.2-r4. I'll try emerging 
r6. One thing.. my Sempron surely supports mmx and sse. I have both of 
those USE flags in my make.conf, but when emerging something, both those 
flags are in the () and are not used... why is that?

Well, give it shot.  But looking at the ChangeLog, I don't see any
references to via driver changes in -r5 or -r6, so I wouldn't hold my
breath that you will see a difference just from the minor bump in the
ebuild version.

However, looking through the ebuild, it looks like the 'via' driver
will be disabled if you use the 'minimal' flag.  So make sure you
don't merge with that in any case!

Flags in () are hard-masked by the profile.  In this case,
/usr/portage/profiles/linux-default/use.mask masks out mmx, mmx2, sse,
and others.  It is then up to the profile-specific mask to unmask them
if they will work there...and at present only the x86 profile does
this, so if you are using the amd64 profile, these flags are simply
disabled.

Ebuilds can still add the appropriate CFLAGS or configure options to
enable mmx/sse however.  The xorg-x11 ebuild does this for the amd64
profile.

Still no luck. I tried compiling VIA Unichrome suppport in the kernel, 
but the kernel version of via_drv.o doesn't move out of /usr/src. 
xorg-x11-6.8.2-r6 doesn't compile via_drv.o and my X is performing very 
badly!

What I don't understand, is why it would work perfectly fine on FC4 and 
not on Gentoo with vesa driver!

I think we have a failure to communicate here....

The via_drv I am talking about is an _x.org_ driver, not a kernel
driver.  It has nothing to do with the kernel sources or rebuilding
the kernel.  It should exist at /usr/lib/modules/drivers/via_drv.o
(along with all other X11 drivers).

I don't understand why you don't have this file.  The only case this
should be missing is if you have USE=minimal.  Could you please post
the output of "emerge -pv xorg-x11"?

Once you have this file, then you will need to update your xorg.conf
Device section and change the Driver option to "via".

The kernel has a DRM driver for via, that (if compiled as a module)
will be installed under /lib/modules as "via.ko".  To load that, you
will modify /etc/autoload.d/kernel-2.6 to add the line "via". 
However, again, this is only for DRI/DRM support, and will almost
certainly require using the X11 via driver, so let's worry about that
later!

I know! My xorg just doesn't want to compile that file! So what I tried 
was to enable the VIA drivers in the kernel. It then compiled both 
drm.ko and via.ko and also via_drv.o, but the via_drv.o never left the 
/usr/src directory.

I surely didn't use the minimal flag. The first time I had enabled 
insecure-drivers and disabled font-server. Then after reading your first 
email, I tried to compile it with the same USE flags as yours.

Already tried that, but of course, no via_drv.o!

Well, the kernel modules have been loaded already...

I noticed one thing, the agpgart option in the kernel is always 
disabled... !x86_64 says the Help for that option. As it is, I have a 
PCI card...

I just can't understand why the file isn't compiled by xorg. Not to 
mention, FC4 uses "vesa" and works perfectly. I wonder what's going on 
with Gentoo :(

Thanks for your help so far,

Possibly because you don't have the 'insecure-drivers' USE flag enabled:

You might as well try it; you can't be much worse off.

Like most binary distros, the FC RPMs probably enable everything
'enableable'. I have no idea why the drivers are considered 'insecure',
but assuming they are (which would not surprise me), it's well within
the realm of possibility that they fall under the "you have to know what
you're doing and decide for yourself' section of the Gentoo design
philosopy (which is the major thrust of the Gentoo design philosopy, so
that doesn't surprise me either).

Why FC 4 would enable them and Gentoo would mark them as insecure....
well, heck-- FC4 uses GCC 4.0 *by default* as I understand it, and we
have it completely masked (and most other distros don't use it either,
afaik, certainly not by default yet). So since FC4 seems to want to live
even further out on the 'bleeding edge' than we are said to do, again,
I'm not surprised that the drivers would be enabled by default, no
matter their status in terms of security, completeness, or stability.

HTH,
Holly

I had insecure-drivers enabled the first time I compiled xorg. I think I 
had disabled it in the subsequent compilations. I found an ebuild with 
VIA Unichrome USE flag and patches added; in the forums. I'll try that 
ebuild because it's been reported to have worked. I'll also make sure 
that I enable insecure-drivers this time! I'll know the results in about 
an hour and half... Hope it works.

Hmmm. Well, I love my Gentoo. I can always use the bleeding edge stuff 
with ~ keywords (As you would already know of course ;))! Anyway, I 
think Mandriva 2006 also uses GCC 4 by default now. It also comes with 
xorg 6.8.9*. I read on xorg.freedesktop.org that the new xorg release 
includes updates from the VIA Unichrome project. I looked into portage 
and yaay! The VIA drivers package is there.. Only, its -amd64. I am on 
AMD64. I'm wondering what to do.

If all fails, I'll have to buy an NVIDIA AGP card I guess. I love Gentoo 
too much to remove it just because of this graphics card issue. (Wise 
choice spending money on an FX5200 just to have Gentoo running??? Well, 
I can always install UT and say to myself, YES! Wise choice indeed :P )

Which is the exactly correct and expected behavior.

Ok, if I am reading the xorg configuration files correctly (which are
a bit complex...to say the least), it seems the via driver is disabled
by default when compiling for the AMD64 architecture.

Too many variables to answer that question...kernel versions, kernel
configuration, kernel patches, frame buffer options, xorg versions,
xorg patches, and so on.  You could try to eliminate some of those
variables by using the same kernel version & .config under both.

Ay! Great idea! I think I'll get the FC4 kernel sources and the .config 
file as well! Let's see how it goes!

Do an 'lsmod' on your FC4 too and compare.

What PCI card?  The Unichrome chip isn't a card.  And it does need 
AGP, via_agp for the 400 chips, amd64_agp for the 800 chips.  See 
the first line of 'lspci' for what chip you have.

Is the via driver present on your FC4?  And if so, have you tried 
using it there?  Maybe it simply doesn't work, by being unable to 
handle 64 bits?

That'd be drm and via

Hmmm. The first line of lspci is "Unknown Device"

00:00.0 Host Bridge: VIA Technologies, Inc.: Unknown Device 0204

And this is my graphics card:

01:00.0 VGA compatible controller: VIA Technology, Inc. S3 Unichrome Pro 
VGA Adapter (rev 01)

Which drivers exactly? As it is, I'm having problems with 2D performance 
and am not really concerned about 3D performance. The drm and via 
modules loaded above are 3D related... Hmmm.

Okay, that's a 800 chip.  You need the amd64_agp module, not the 
via_agp one.  To see what you've configured, please post the output 
of 'egrep "AGP|DRM|VIA" /usr/src/linux/.config'.

Hrm... read back in the thread: /usr/lib/modules/drivers/via_drv.o.
(Or with an X11/ in the path.)  It's the Xorg 2D via driver.

You don't want the via driver for now, use the vesa one.  But you 
were complaining that Gentoo didn't have the Xorg via driver 
installed, that's why I asked if FC4 did.  I guess not, as probably 
it doesn't work for 64 bits, which is why FC4 uses the vesa driver.

To help a bit more: post the output of 'emerge --info'.
