Salut Andrei,

Mai intai, nu am destule informatii sa afirm cu precizie cauza.

Daca e de vina tentativa sistemului de a depista modul grafic : adauga nomodeset la parametrii de boot. daca dupa reboot nu se mai intampla, e ok, daca nu, cauta totusi in log cauza. 

outputul de la unity --reset

Dupa cum arata, unity a luat-o pe carari nebanuite :).

citez de la bug #943083 :

1. switch to tty1 and log in as myself

2. rm -rf ~/.compiz (in order to recursively delete session logs....there might also be ~/compiz-1 and so on --> delete all!)

3. sudo service lightdm restart

4. log in using the standard greeter again

Ști că eu sunt "neinstruit".

Ajută-mă să ițî dau mai multe amănunte dacă trebuie.

Mersi

Incearca intai cele scrise inainte.

Daca nu rezolva, zi-mi ce rezulta dupa :

# uname -r

# cat /proc/cmdline

si ataseaza dmesg.txt dupa

# dmesg > dmesg.txt

După cum vezi nu a reușit.

Acuma ecranul pâlpâie după login screen.

Înainte pâlpâia înainte de login screen.

 andrei@home:~$ uname -r
3.2.0-38-generic-pae
andrei@home:~$ cat /proc/cmdline
BOOT_IMAGE=/boot/vmlinuz-3.2.0-38-generic-pae root=UUID=71a31fd0-e6a9-43a7-bf95-514f6951c3de ro quiet splash vt.handoff=7

Poti sa incerci sa setezi "vesa" ca Driver si sa vezi daca mai apare flicker:

http://ubuntuforums.org/showthread.php?t=1270209

Dezactiveaza 3d-ul (daca e activat).

Ideea care vreau sa o exprim aici e sa incerci sa incerci cu o
configuratie minimala si apoi sa adaugi optiuni.

As face asa:

1. vesa
2. <driverul tau> in loc de vesa
3. <driverul tau> cu 3d si alte chestii

Daca apar probleme la un pas poti sa incerci si o interfata de linux
(recomand lxde ca e mai soft).

Bafta,
Iulian

Ce bizar, dmesg are un mesaj care indica faptul ca modelul tau de chipset intel n-ar fi suportat de driver :

[    0.455609] pciehp: PCI Express Hot Plug Controller Driver version: 0.4

[    0.455709] intel_idle: MWAIT substates: 0x2220

[    0.455711] intel_idle: does not run on family 6 model 23

Totusi, n-as asocia asta cu ce zici ca patesti.

Nomodeset nu e adaugat ca parametru la kernel (cat / proc/cmdline nu-l indica prezent)

$ sudo nano /etc/default/grub

in loc de GRUB_CMDLINE_LINUX="" pune GRUB_CMDLINE_LINUX="nomodeset" si salveaza

$ sudo update-grub

reboot

$ sudo cat /proc/cmdline

trebuie sa indice nomodeset "root=UUID=71a31fd0-e6a9-43a7-bf95-514f6951c3de ro quiet splash vt.handoff=7 nomodeset"

(nomodeset

The newest kernels have moved the video mode setting into the kernel. So all the programming of the hardware specific clock rates and registers on the video card happen in the kernel rather than in the X driver when the X server starts.. This makes it possible to have high resolution nice looking splash (boot) screens and flicker free transitions from boot splash to login screen. Unfortunately, on some cards this doesnt work properly and you end up with a black screen. Adding the nomodeset parameter instructs the kernel to not load video drivers and use BIOS modes instead until X is loaded. )
