LinuxQuestions.org - [SOLVED] Cannot get higher screen resolution

Hi,
Running Slackware 12.2, KDE on HP dv6t notebook.

The highest resolution I get is 1024x768 though it supports 1366x768. When I startx the following is in my Xorg.0.log.

Code:

 

(II) VESA(0): Supported additional Video Mode:

(II) VESA(0): clock: 72.3 MHz  Image Size:  353 x 198 mm

(II) VESA(0): h_active: 1366  h_sync: 1414  h_sync_end 1446 h_blank_end 1526 h_border: 0

(II) VESA(0): v_active: 768  v_sync: 770  v_sync_end 775 v_blanking: 790 v_border: 0

(II) VESA(0):  SAMSUNG

(II) VESA(0):  160AT02-H02

(II) VESA(0): EDID (in hex):

(II) VESA(0):        00ffffffffffff004ca34c3500000000

(II) VESA(0):        00120103802314780a87f594574f8c27

(II) VESA(0):        27505400000001010101010101010101

(II) VESA(0):        00313630415430322d4830320a2000ab

(II) VESA(0): EDID vendor "SEC", prod id 13644

(II) VESA(0): Printing DDC gathered Modelines:

(II) VESA(0): Modeline "1366x768"x0.0  72.33  1366 1414 1446 1526  768 770 775 790 -hsync -vsync (47.4 kHz)

So I added the following ModeLine into my xorg.conf.

Code:

# **********************************************************************

# Monitor section

# **********************************************************************



# Any number of monitor sections may be present



Section "Monitor"



    Identifier  "My Monitor"



# HorizSync is in kHz unless units are specified.

# HorizSync may be a comma separated list of discrete values, or a

# comma separated list of ranges of values.

# NOTE: THE VALUES HERE ARE EXAMPLES ONLY.  REFER TO YOUR MONITOR'S

# USER MANUAL FOR THE CORRECT NUMBERS.



    HorizSync  31.5 - 64.3



#    HorizSync        30-64        # multisync

#    HorizSync        31.5, 35.2    # multiple fixed sync frequencies

#    HorizSync        15-25, 30-50  # multiple ranges of sync frequencies



# VertRefresh is in Hz unless units are specified.

# VertRefresh may be a comma separated list of discrete values, or a

# comma separated list of ranges of values.

# NOTE: THE VALUES HERE ARE EXAMPLES ONLY.  REFER TO YOUR MONITOR'S

# USER MANUAL FOR THE CORRECT NUMBERS.



    VertRefresh 50-100



    ModeLine "1366x768"  72.33  1366 1414 1446 1526  768 770 775 790

# Standard VGA Device:

    VendorName        "Unknown"

# The chipset line is optional in most cases.  It can be used to override

#    Chipset        "generic"



# The Driver line must be present.  When using run-time loadable driver

# modules, this line instructs the server to load the specified driver

# module.  Even when not using loadable driver modules, this line

# indicates which driver should interpret the information in this section.



    Driver    "vga"

# The BusID line is used to specify which of possibly multiple devices

# this section is intended for.  When this line isn't present, a device

# section can only match up with the primary video device.  For PCI

# devices a line like the following could be used.  This line should not

# normally be included unless there is more than one video device

# intalled.



#    BusID      "PCI:0:10:0"

    Device      "* Generic VESA compatible"

    Monitor    "My Monitor"

    DefaultDepth 24



    Subsection "Display"

    Subsection "Display"

    EndSubsection

EndSection

However, startx fails to load the "1366x768" mode. The log shows the following.

Code:

(II) VESA(0): Total Memory: 1023 64KB banks (65472kB)

(II) VESA(0): My Monitor: Using hsync range of 31.50-64.30 kHz

(II) VESA(0): My Monitor: Using vrefresh range of 50.00-100.00 Hz

(II) VESA(0): Not using mode "1366x768" (no mode of this name)

(--) VESA(0): Virtual size is 1024x768 (pitch 1024)

(**) VESA(0): *Built-in mode "1024x768"

(**) VESA(0): *Built-in mode "800x600"

(**) VESA(0): *Built-in mode "640x480"

Another thread suggested not to add the ModeLine at all. This didn't work too. I got the same error "no mode of this name"

Any suggestions?
Also, I'm using a generic "vesa" driver, could that be a problem?

Thanks in advance,

Ash.
