Graphic Issue probably correlate with xorg

Hi, I have installed slackware, the installation went well, however, when I try to generate an automatic xorg.conf configuration, I get

Code:

(++) Using config file: "/root/xorg.conf.new"

(==) Using system config directory "/usr/share/x11/xorg.conf.d"

Number of created screens does not match number of detected devices.

Configuration failed.

(EE) Server terminated with error (2). Closing log file.

with the generated file xorg.conf.new

When I try to start x with startx or xinit, I see the chosen desktop, but with huge letters on menu so much that only a little part is showed. There is no blackscreen, the cursor is correctly displayed... Thanks in advance

Your not starting X as root are you? Don't. Run X as user. You did make a limited user?
See:
man useradd
also the slack docs.

You also have not told a thing about your video hardware.
What is the output of

Code:

lspci -k

What does xrandr report?
See:
man xrandr

Does Slackware need a xorg.conf to work?

Thanks for answer, so, I just created an normal user, and starting X server with it generate same result than root user.
lspci -k generates this

I have an intel Celeron g3930 with embedded gpu HD Graphics 610

Did you leave something off? That does not show what kernel module you have loaded for that graphics hardware.

Kernel modesetting may work best with that intel hardware, if it is a recent kernel. lsmod will show you what's loaded.

What does xrandr show you? See: man xrandr
Also

Code:

xdpyinfo | grep -B 2 resolution

See what kernel module you have loaded, if it is the right one,
resolution and dpi that you have. Go from there.

Maybe a Slacker can tell you more.

Have you read the docs?

Hello,

Which version of Slackware ? With recent one there is no need of xorg.conf
I have only keyboard defined in :
> ls /etc/X11/xorg.conf.d
90-keyboard-layout-evdev.conf

> cat 90-keyboard-layout-evdev.conf
Section "InputClass"
Identifier "keyboard-all"
MatchIsKeyboard "on"
MatchDevicePath "/dev/input/event*"
Driver "evdev"
Option "XkbLayout" "fr"
#Option "XkbVariant" ""
Option "XkbOptions" "terminate:ctrl_alt_bksp"
EndSection

# READ THIS FOR CUSTOM KEYBOARD INFORMATION
#
# If you want to add a custom model/layout/variant to X, you will need to COPY
# this file to /etc/X11/xorg.conf.d/ and edit that copy. After editing it to
# suit, you will need to restart X.
#
# Here's an example of the lines from above:
#
# Section "InputClass"
# Identifier "keyboard-all"
# MatchIsKeyboard "on"
# MatchDevicePath "/dev/input/event*"
# Driver "evdev"
# Option "XkbLayout" "us"
# Option "XkbVariant" "intl"
# Option "XkbOptions" "compose:rwin,terminate:ctrl_alt_bksp"
# EndSection
#
# Many desktop environments, including KDE and Xfce, have their own methods to
# configure keyboard layouts and such if you'd like to use them.
#
# If you prefer to use the "old" way of configuring keyboards (without input
# device hotplugging), then you'll need to add the following lines to the
# ServerFlags section of /etc/X11/xorg.conf:
# Option "AllowEmptyInput" "false"
# Option "AutoAddDevices" "false"
# Option "AutoEnableDevices" "false"
# Alternatively, you can break this up into separate "stubs" in the xorg.conf.d/
# directory, but that's your call. Assuming you elect to keep a monolithic
# /etc/X11/xorg.conf file, you can now edit the Keyboard section as usual.

Which is a modified copy which french layout of the master in /usr/share/X11/xorg.conf.d
