Issue with users accessing video card and /dev/nvram

Nick234 · 2008-12-30 19:33:07

Hello,

I have Lenovo x60s and i can't access with normal user (group users) the file

/dev/nvram

ever I restart de computer have execute "chmod 777 /dev/nvram" for fallowing access for users

and with users i can't use video i810 alone use vesa

with root i can use driver i810 on xorg, why??

I don't understand?!?!?!

did u add the user to the video group?

so for example try as root user

# gpasswd -a okplayer02 video

replace okplayer02 with your username

Nick234 · 2009-01-01 14:08:39

well for one there is no i810 driver

u have the intel driver which replaces the i810 what do u have in ur xorg in the driver section for ur graphics card

what is ur reason for accessing the /dev/nvram ??

The problem with my video is with root i can play games 3D, with users i can't, my config video card on xorg:

Section "Device"
        ### Available Driver options are:-
        ### Values: <i>: integer, <f>: float, <bool>: "True"/"False",
        ### <string>: "String", <freq>: "<f> Hz/kHz/MHz"
        ### [arg]: arg optional
        #Option     "ShadowFB"               # [<bool>]
        #Option     "DefaultRefresh"         # [<bool>]
        #Option     "ModeSetClearScreen"     # [<bool>]
    Identifier  "Card0"
    Driver      "vesa" ---->> Now I write "VESA", while I write i810 i can't execute "startx" with normal user
    VendorName  "Intel Corporation"
    BoardName   "Mobile 945GM/GMS, 943/940GML Express Integrated Graphics Controller"
    BusID       "PCI:0:2:0"
EndSection

the /dev/nvram is device when i use especial keys of keyboard on my notebook,

ever restart my pc the permissions change, I have execute "chmod 777 /dev/nvram" else i can't use with normal user.

i think the udev always create this device on start and always create with the permission alone read and write for root, but I just find that the group is kmen and I add my user in the group.

I restart system and verify the result.

well i tell u the name of the driver is

xf86-video-intel

if u install it like so pacman -S xf86-video-intel and make sure u put "intel" in the place of "vesa"

u should be better off that way

Nick234 · 2009-01-01 16:58:22

Well...

I make it, but my driver is not intel but yes i810,
but it is not the problem...

The real problem is that while I startx with root and play games, the quality game is very good but normal user is very very very lowwwwwwwwww!!!!!!!!!

look like that while play with normal user the acelerate graphics of video card not work.

okplayer02 · 2009-01-01 18:03:04

well again i can tell u there is no i810 driver just the intel which replaced the older i810

http://www.archlinux.org/packages/extra … deo-intel/

check the link otherwise i cannot help you much if u insist to use i810 which does not exist anymore

happy new year

okplayer02 · 2009-01-01 18:21:32

well i stand corrected according to the wiki u can use i810

http://wiki.archlinux.org/index.php/Intel_Graphics

take a look for urself

Nick234 · 2009-01-02 00:24:06

yeh!

I use the tutorial in http://wiki.archlinux.org/index.php/Intel_GMA_945
my intel is 945GM, and stay very fast!

but I discovery the driver intel i810 on pacman change name, not is xf86-driver-i810 the name now is xf86-driver-intel and the 915resolution write on link up, not stay avaliable on pacman, I think stay obsolete.

thanks
