Anyone else think X has a performance problem ?
by John Wendel
I first noticed the X slowdown when I installed F8. I've used every
version of Fedora, and I noticed that the user experience with F8 was
not as smooth as earlier versions. I spend most of my day hacking code
in vi, so 2D video performance is important to me. I care nothing about
3D video.
When I updated my work box (P III - 512 MB) from FC6 to F10, the
slowdown was so bad that I was tempted to reinstall FC6. Basically, F10
converted a very usable older box into something that was almost unusable.
So, I decided to collect a few numbers and post them to see if we can
get a little discussion going and maybe provide some feedback to some
developers who could actually improve things.
I've got boxes at home running FC6, F8, and F10. The FC6 box is an old
AMD Athlon 2Ghz 1.5GB memory, the F8 box is a P4 3 Ghz 2GB memory, and
the F10 box is an Intel Core2 2.2 Ghz 4GB memory.
For the test, I created a 1,000,000 line (80 byte lines, 80 MB) text
file and timed "cat file" on all the boxes, with and without X. I ran
the test several times and reported the fastest time. I also tried
turning off anti-aliased text, but that was actually slower.
Bottom line, FC6 running X was 6 times faster than F8 and over 8 times
faster than F10. I know that there have been many, many improvements in
Fedora over the years, but X looks like it's taking a big step backward.
And don't tell me the eye-candy is much better, because I don't care.
If I'm full of shit, please let me know how I can get better X performance.
Maybe someone with ATI video could run the test and post some results.
Regards,
John

Missing Hardware After Update
by Gene Poole
I've updated my primary system from the base Fedora 9 to the latest
maintenance level. This Fedora 9 is running on a custom built box with a
AMD Phenom Quad-Core, 8 GB RAM, a HP RW CD/DVD dual layer with
lightscribe.
After the update, I see that base device for the DVD isn't there
(/dev/sr0)! Does anyone have a idea how I can get it back?
TIA,
Gene

Speaking of finding printers...
by Tom Horsley
Is there any way I can convince it to NOT find a printer?
Some system somewhere claims to have a shared printer on
it, but it isn't a printer I want to use or even know where
is located. I'd really like it to not be in the list of
printers, but the ever so "helpful" software insists
on finding it because it can.
Is some arcane iptables rule the only way to make this
printer go away? Anyone have an iptables example to
achieve that?

"normal" boot/shutdown in f10
by François Patte
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
Bonjour,
I am wondering how to get a non-graphical boot in fedora 10.
In the previous version (up to f9), I used to disable graphical boot in
/etc/sysconfig/init
# Turn on graphical boot
GRAPHICAL=no
#
And I could get a black screen with the status of all starting services
Now we don't have this choice:
# color => new RH6.0 bootup
# verbose => old-style bootup
# anything else => new style bootup without ANSI colors or positioning
BOOTUP=color
#BOOTUP=verbose
#
If I choose "BOOTUP=verbose" it is the very old style bootup from redhat
4 (or 5 I don't remember) where you cannot read anything.
Also, at shutdown, when GRAPHICAL was set to "no", you could see all
status of shuting down services.
Now this works randomly: sometimes you can see this, sometimes nothing
is displayed until the system stops. I the later case, for me, I have
problems to reboot with the software RAID 1 I installed on my box. I
suppose that md services do not shutdown propperly but I cannot see it.
Thanks for answering.

The system freezes when switching session
by Pedro Jose
Hello everbody:
I use Fedora 10 i386 in a Compaq Presario Notebook C735EM.
The system is updated, and my desktop is gnome with compiz fusion enabled.
The graphics card is intel.
The problem I have is that when I change the current user session to another
user, the system freezes, crashes.
All I can do is move the mouse. I can not close the X. I can not move to
terminal Cntr + Alt + F1
I tried to do before turning off compiz fusion, but also freezes.
In a virtual machine that I can not, so I guess it is problem of my laptop.
Can someone help me?
Sorry for my english. I´m spanish.

why is gdm ignoring dpms
by François Patte
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
Bonjour,
I have dpms enabled in xorg.conf file:
Section "Monitor"
# HorizSync source: edid, VertRefresh source: edid
Identifier "Monitor0"
VendorName "LG"
ModelName "LG L1920P"
HorizSync 30.0 - 71.0
VertRefresh 56.0 - 75.0
Option "DPMS"
EndSection
log confirm this fact (Xorg.0.log):
(**) Option "dpms"
(**) NVIDIA(0): DPMS enabled
But gdm refuses to apply this. Why.
In fact all gnome is ignoring the global X setting: I have to enable
dpms in bash config file adding
xset dpms 300 600 900
But if the computer stays on login screen no dpms is working....
running f10 fully updated today.

system-config-printer can't find my remote printer ??
by Bill Case
Hi;
I feel foolish posting here. This should be simple to do. But I am
stumped. I have googled etc. and found nothing helpful.
I have a two computer home LAN. The network is properly set up. I can
ping and ssh in both directions.
I have a working HP Photosmart C4200 series printer connected by USB to
my BASEMENT computer. I am trying to set up printing for the UPSTAIRS
computer over the LAN. system-config-printer on the UPSTAIRS computer
does not detect the basement printer and none of the set up options it
gives seems to work.
I would like the printer setup to 'just work' before I turn the UPSTAIRS
computer over to a non-IT person who has just come off of using
WindowsXP.
I am flumexed.

Redhat up2date rpms to date
by Paul Ward
Hi,
I am looking for an easy way to update over 20 servers via up2date.
As it will take me several days to update all the servers is their an
easy way to add them to a rhn channel that will not accept any newer
packages as of a date and time I choose, as I worry that a new package
or even kernel maybe released in the middle of my updating /
downloading rpms to the servers.
I am going to use # up2date -du to start off with, however this could
still cause a problem for me.
Thanks

OS "hiccups"
by Smith, Herb
All,
I'm running Fedora 10 and have been very happy with it. Within the last
week, however, the OS seems to be experiencing momentary "hangups" of
some sort where all activity stops for 10 or 15 seconds. The cursor
won't move, web pages won't scroll, etc. This occurs not only in
Firefox, but generally regardless of what I'm doing.
Does anyone have any idea what could be causing this?
TIA,
Herb
