Unable to change screen resolution on Packard Bell Easy Note

screen resolution

Best Answer The waiter, 08 November 2017 - 07:15 PM

Hello

 

I have an old Lenovo S12 NTB and had also some troubles with the video drivers as there is all from VIA. CPU, GPU (VIA Chrome 9), everything. I am unable to install BL 4.x on it because I see no desktop, just a black screen. I won't fight with it because my daughter uses it from time to time, but I had to install BL 3.2.1 Legacy and have no screen issues. Maybe a tip for you.

Hi, I have just installed Bodhi Legacy on my laptop Easy Note ( Packard Bell, RAM: 437 Mo, Intel® Celeron® M 1500 MHz). When it starts to boot screen resolution seems fine, but once the system finally enter, screen resolution change to the very basic 640x480.

Based on this page I tried the command 'xrandr -q' and I get:

xrandr: Failed to get size of gamma for output default
Screen 0: minimum 640x480, current 640 x 480, maximum 640 x 480
default connected 640x480+0+0 0mm x 0mm
   640x480     0.00*

To know the graphic card, I did that:

lspci | grep "VGA compatible controller"
01:00.0 VGA compatible controller: VIA Technologies, Inc. CN400/0/PN880 [S3 Unichome Pro] (rev 02)

For information, when I start I get this message (during the boot) before to arrive on the desktop:

[  13.8966371] via ircc 0000:00:11.0: can't enable device: BAR 13[io 0x1000-0x107f] not claimed

Thanks for your help





A big thank you to everyone who contributes to Bodhi Linux

Modeline "1024x600_60.00" 49.00 1024 1072 1168 1312 600 603 613 624 -hsync + vsync

The link you have is useful for people who have the sismedia graphics chip; yours is a VIA. That certain resolution cannot be obtained by xrandr alone; xrandr will work as the second or third step. Others might propose an alternate solution; feel free to try them out. But also try a different search this time, with 'VIA' included.


Unsolicited advice for learning linux, that won't cost you anything

It looks like this device requires a closed source driver. Can you try giving the instructions here a try? https://help.ubuntu....unity/UniChrome

Bodhi 4 is Ubuntu 16.04 based.

Hi. Thanks for your help. I think also I need a closed source driver. The links that Jeff provided is outdated.

I founded a driver for the VIA Technologies Card but on ArchLinux....

I come back with a question. With BL 3.2.1 Legacy, just after thte boot I get this screen during few  seconds.

I remembered that with the BL Legacy 4.3.1 I get this screen by tipping one key of keyboard ( Fx or ?) and I managed to have the right resolution. Do you  know wich key I shall press to have this screen GNU GRUB ?   Thanks

You shouldn't have to press a key to get the GRUB bootloader screen, I don't believe. You should by default see it for 8 seconds at boot every time.

No, single OS did skip the grub screen. Holding Shift during boot brings it up. This was a "feature" of Grub.

 

Enjoy,

OTOH, I think the user wants to have it skipped on his machine.

 

You can change the time grub is visible in the file /etc/default/grub

The value in the line: GRUB_TIMEOUT=(number) can be changed. If I remember correctly a value =0 skipped it.

You need root access to do this and must not forget to save the file.

 

Enjoy,

Charles
