Not working with 2 HP monitors #137

Closed foxt closed 1 year ago

foxt commented 4 years ago

I know these monitors are DDC compatible, as I have a script that works with these monitors connected to macOS.

I have two HP monitors, the 22xi and 22vx, both fail to control via ddcutil

DDC communication failed for monitor on I2C bus /dev/i2c-5

*** Primary Check 1: Identify video card and driver ***

*** Primary Check 2: Check that /dev/i2c-* exist and writable ***

Current user: root (0)

Checking /dev/i2c-* devices...

Unless the system is using the AMD proprietary driver fglrx, devices /dev/i2c-*
must exist and the logged on user must have read/write permission for those
devices (or at least those devices associated with monitors).

Typically, this access is enabled by:
  - setting the group for /dev/i2c-* to i2c
  - setting group RW permissions for /dev/i2c-*
  - making the current user a member of group i2c

Alternatively, this can be enabled by just giving everyone RW permission
The following tests probe for these conditions.

Checking for /dev/i2c-* devices...
   crw-rw---- 1 root i2c 89, 0 Aug  7 03:12 /dev/i2c-0
   crw-rw---- 1 root i2c 89, 1 Aug  7 03:12 /dev/i2c-1
   crw-rw---- 1 root i2c 89, 2 Aug  7 03:12 /dev/i2c-2
   crw-rw---- 1 root i2c 89, 3 Aug  7 03:12 /dev/i2c-3
   crw-rw---- 1 root i2c 89, 4 Aug  7 03:12 /dev/i2c-4
   crw-rw---- 1 root i2c 89, 5 Aug  7 03:12 /dev/i2c-5
   crw-rw---- 1 root i2c 89, 6 Aug  7 03:12 /dev/i2c-6
   crw-rw---- 1 root i2c 89, 7 Aug  7 03:12 /dev/i2c-7

Current user (root) has RW access to all /dev/i2c-* devices.

Checking for group i2c...
   Group i2c exists
   Current user is root, membership in group i2c not needed

Looking for udev rules files that reference i2c:
   Checking rules directory /lib/udev/rules.d:
      /lib/udev/rules.d/60-autosuspend-chromiumos.rules:SUBSYSTEM!="i2c|pci|usb", GOTO="autosuspend_end"
      /lib/udev/rules.d/60-autosuspend-chromiumos.rules:SUBSYSTEM=="i2c", GOTO="autosuspend_i2c"

      /lib/udev/rules.d/60-sensor.rules:SUBSYSTEM=="iio", KERNEL=="iio*", SUBSYSTEMS=="usb|i2c|platform", \
   Checking rules directory /run/udev/rules.d:
      grep: /run/udev/rules.d/*rules: No such file or directory
   Checking rules directory /etc/udev/rules.d:
      grep: /etc/udev/rules.d/*rules: No such file or directory

*** Primary Check 3: Check that module i2c_dev is loaded ***

Checking for module i2c_dev...
   Module i2c-dev is built into kernel

*** Primary Check 4: Driver specific checks ***

Performing driver specific checks...
No driver specific checks apply.

The DDC response packets that ddcutil reads are invalid. Sometimes the packets are entirely zero, sometimes they have a repeated byte in them. Typically this indicates a marginal DDC implementation in the monitor.

Things to try:

Option --sleep-multipler 4

Some monitors need extra time to prepare a response. This option increases the time ddcutil waits between sending a request to the monitor and trying to read a response. With a value or 4, a 200 ms wait mandated by the DDC/CI specification becomes 800 ms.

Option --maxtries "0,15,0"

I2C is an inherently unreliable protocol. This option increases the number of times ddcutil retries a write request/read response sequence, in this case from the default 10 to 15.

If neither of these solve the problem, execute the following command and send the output as an attachment:

$ ddcutil detect --verbose --stats --trace i2c --trace ddcio
