[BUG] 4th Gen Intel iGPU can't get a reading on BTOP meanwhile 2nd Gen Intel iGPU can for some reason?

Read the README.md and search for similar issues before posting a bug report!

Any bug that can be solved by just reading the prerequisites section of the README will likely be ignored.

Describe the bug

I can't seem to see the Intel GPU usage on the 4th Gen iGPU (4600) than on 2nd gen (3000)

System info being compared

2nd Gen machine:

• Acer 5750, Intel i5-2310M, Intel HD 3000, no additional GPU onboard
• Arch Linux, all updated

4th gen machine

• Fujitsu Lifebook A574M, i3-4100M, Intel HD 4600, no additional GPU onboard (more like only Intel GPUs on the lineup)
• Arch Linux, all updated

To Reproduce

• install btop + intel-gpu-tools + tlp

Expected behavior

4th gen gets a reading (the 2nd gen already has a reading about GPU %)

Screenshots

Second gen has no logs for some reason?

Note: The snap uses: ~/snap/btop/current/.config/btop

(try running btop with --debug flag if btop.log is empty)

GDB Backtrace

If btop++ is crashing at start the following steps could be helpful:

(Extra helpful if compiled with make OPTFLAGS="-O0 -g")

1. run (linux): gdb btop (macos): lldb btop

2. r to run, wait for crash and press enter if prompted, CTRL+L to clear screen if needed.

3. (gdb): thread apply all bt (lldb): bt all to get backtrace for all threads

4. Copy and paste the backtrace here:

for some reason ill put #942 here instead because its the fix

use sudo
