Nvidia & brightness control
Dears,
this is my first post here and i hope to find my answers here :) my os is redhat 6 and i cant get the brightness to change the other funtions are working my laptop is toshiba thank you very much |
What is the model number of your laptop? Are you using acpi? Without the model number, I can roughly guess that this is either a video driver and/or config issue; Could you also provide us the output of the following commands?
Code:
uname -a |
thank you very much for your help
it is probably a driver issue as when i do modprobe nvidia FATAL: Error inserting nvidia_302_17 (/lib/modules/2.6.32-279.el6.x86_64/updates/drivers/video/nvidia/nvidia-302_17.ko): No such device uname -a Linux dhcppc0 2.6.32-279.el6.x86_64 #1 SMP Wed Jun 13 18:24:36 EDT 2012 x86_64 x86_64 x86_64 GNU/Linux lspci -k 00:00.0 Host bridge: Intel Corporation 2nd Generation Core Processor Family DRAM Controller (rev 09) Subsystem: Toshiba America Info Systems Device fc90 00:01.0 PCI bridge: Intel Corporation Xeon E3-1200/2nd Generation Core Processor Family PCI Express Root Port (rev 09) Kernel driver in use: pcieport Kernel modules: shpchp 00:16.0 Communication controller: Intel Corporation 6 Series/C200 Series Chipset Family MEI Controller #1 (rev 04) Subsystem: Toshiba America Info Systems Device fc30 00:1a.0 USB controller: Intel Corporation 6 Series/C200 Series Chipset Family USB Enhanced Host Controller #2 (rev 04) Subsystem: Toshiba America Info Systems Device fc30 Kernel driver in use: ehci_hcd 00:1b.0 Audio device: Intel Corporation 6 Series/C200 Series Chipset Family High Definition Audio Controller (rev 04) Subsystem: Toshiba America Info Systems Device fc30 Kernel driver in use: snd_hda_intel Kernel modules: snd-hda-intel 00:1c.0 PCI bridge: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Root Port 1 (rev b4) Kernel modules: shpchp 00:1c.1 PCI bridge: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Root Port 2 (rev b4) Kernel modules: shpchp 00:1d.0 USB controller: Intel Corporation 6 Series/C200 Series Chipset Family USB Enhanced Host Controller #1 (rev 04) Subsystem: Toshiba America Info Systems Device fc30 Kernel driver in use: ehci_hcd 00:1f.0 ISA bridge: Intel Corporation HM65 Express Chipset Family LPC Controller (rev 04) Subsystem: Toshiba America Info Systems Device fc30 Kernel modules: iTCO_wdt 00:1f.2 SATA controller: Intel Corporation 6 Series/C200 Series Chipset Family 6 port SATA AHCI Controller (rev 04) Subsystem: Toshiba America Info Systems Device fc30 Kernel driver in use: ahci Kernel modules: ahci 00:1f.3 SMBus: Intel Corporation 6 Series/C200 Series Chipset Family SMBus Controller (rev 04) Subsystem: Toshiba America Info Systems Device fc30 Kernel modules: i2c-i801 01:00.0 VGA compatible controller: NVIDIA Corporation Device 0a7a (rev a2) Subsystem: Toshiba America Info Systems Device fc90 Kernel driver in use: nouveau Kernel modules: nvidia-302_17, nouveau, nvidiafb 01:00.1 Audio device: NVIDIA Corporation High Definition Audio Controller (rev a1) Subsystem: Toshiba America Info Systems Device fc90 Kernel driver in use: snd_hda_intel Kernel modules: snd-hda-intel 02:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd.

well the nvidia 302 driver is very old
the current nvidia kmod for el6 is the 310 for red hat enterprise linux 6.4 ( the current ) yum should show 310 ( if you installed elrepo ) with the elrepo installed ( it has the nvidia kmod ) Code:
yum search nvidia you will also need to blacklist the opensource " nouveau" driver and rebuild the boot image without the nouveau driver search red hat knowlage base for the instructions this is RHEL6 so you do have the required and paid for support contract https://access.redhat.com/search/quick you will need to login to red hat with the credentials you set up when you bought the required support contract |
thank you very much
i downloaded the latest nvidia driver and it was 310 i installed it and it worked :) |
