[Regression] Xorg server crashes from version 2:21.1.3-2ubuntu2.4

[Aurimas Fišeras]

Xorg server crashes on Dell Vostro V3750 notebook (integrated Intel GPU + Nvidia GeForce GT 525M) after upgrading xserver-xorg-core to 2:21.1.3-2ubuntu2.4.

After some testing we determined that the crash is caused by a patch re-calculate-the-clock-and-refresh-rate.diff added in version 2:21.1.3-2ubuntu2.4 (LP: #1996490).
